Integrated circuits (ICs) are classified according to their levels of complexity: small-scale integration (SSI), medium-scale integration (MSI), large-scale integration (LSI) and very large-scale integration (VLSI). They are also classified according to the technology employed for their fabrication (bipolar, N metal oxide semiconductor (NMOS), complementary metal oxide semiconductor (CMOS), etc.Stanlyhttp://www.blogger.com/profile/17984769319085340260noreply@blogger.com0tag:blogger.com,1999:blog-445788637623239574.post-48678017707297273502012-11-15T21:27:00.003+08:002012-11-15T21:27:44.069+08:00N AND P TYPE MATERIALS BASIC INFORMATION
When an impurity like arsenic is added to
germanium it will change the germanium crystal lattice in such a way as to
leave one electron relatively free in the crystal structure. Because this type
of material conducts by electron movement, it is called a negative carrier
(N-type) semiconductor.
Pure germanium may be converted into an N-type
semiconductor by doping it with a donor Stanlyhttp://www.blogger.com/profile/17984769319085340260noreply@blogger.com0tag:blogger.com,1999:blog-445788637623239574.post-31227798466747226242012-11-15T21:27:00.001+08:002012-11-15T21:27:05.162+08:00THE INERTIAL NAVIGATION SYSTEM (INS) BASIC INFORMATION
The inertial navigation system provides
information similar to that supplied by a doppler system, and it also gives
readings of latitude and longitude when desired. The inertial system utilizes
extremely sensitive gyros and accelerometers to develop signals from which
navigation information is computed.
The heart of the Collins INS-61 inertial
system is the inertial sensor unit (ISU) which Stanlyhttp://www.blogger.com/profile/17984769319085340260noreply@blogger.com0tag:blogger.com,1999:blog-445788637623239574.post-70570319176227425992012-11-15T21:26:00.003+08:002012-11-15T21:26:34.256+08:00AIRCRAFT MARKER BEACON AND RECEIVERS BASIC INFORMATION
In order to provide a pilot with an
indication of his distance from the runway, marker-beacon transmitters are
installed with the outer-marker transmitter at approximately 5 miles from the
runway and the mid-marker approximately 5 mile from the end of the runway.
The marker-beacon transmitter operates at a
frequency of 75 MHz and produces both aural and visual signals. The

A homing guidance system requires that a
missile contain such electronic sensing and control devices that the missile
will seek a target on its own without the need for command signals from outside
the missile. Homing systems are classified as active, semiactive, and passive,
depending upon the nature of the sensing and controlling mechanisms.

Java is uniquely suited for network
programming. It provides solutions to many issues that are difficult to solve
using other programming languages. Java applets have a higher level of safety
than that of similar software packages.
Java makes network programming much easier.

MPI point-to-point communication routines
are utilized for data communications between a sending processor and a
receiving processor. The argument list of these routines takes one of the
following formats:

BCD counters are used when the application
involves the counting of pulses and the result of counting is to be displayed
in decimal. A single-stage BCD counter counts from 0000 (decimal equivalent
‘0’) to 1001 (decimal equivalent ‘9’) and thus is capable of counting up to a
maximum of nine pulses.
The output in a BCD counter is in binary
coded decimal (BCD) form. The BCD output needs to be Stanlyhttp://www.blogger.com/profile/17984769319085340260noreply@blogger.com0tag:blogger.com,1999:blog-445788637623239574.post-40180552211662480952012-11-14T19:58:00.004+08:002012-11-14T19:58:56.742+08:00DESIGNING COUNTERS WITH ARBITRARY SEQUENCES BASICS
So far we have discussed different types of
synchronous and asynchronous counters. A large variety of synchronous and
asynchronous counters are available in IC form, and some of these have been
mentioned and discussed in the previous sections.
The counters discussed hitherto count in
either the normal binary sequence with a modulus of 2N or with slightly altered
binary sequences where one Stanlyhttp://www.blogger.com/profile/17984769319085340260noreply@blogger.com0tag:blogger.com,1999:blog-445788637623239574.post-73501652600002826872012-11-14T19:58:00.000+08:002012-11-14T19:58:03.546+08:00FLIP FLOP EXCITATION TABLE
The excitation table is similar to the
characteristic table that we discussed on flip-flops. The excitation table
lists the present state, the desired next state and the flip-flop inputs (J, K,
D, etc.) required to achieve that.
The same for a J-K flip-flop and a D
flip-flop are shown in Tables 11.7 and 11.8 respectively. Referring to Table

Hard disks are nonvolatile random access
secondary data storage devices, i.e. the desired data item can be accessed
directly without actually going through or referring to other data items. They
store the data on the magnetic surface of hard disk platters.
Platters are made of aluminium alloy or a
mixture of glass and ceramic covered with a magnetic coating. Figure 15.32

Input/output ports are used to connect the
computer to external devices. Input and output standards described in the
previous sections are referred to as external bus standards.
In addition to these external buses,
computers also have internal buses that carry address, data and control signals
between the CPU, cache memory, SRAM, DRAM, disk drives, expansion slots and
other internal devicesStanlyhttp://www.blogger.com/profile/17984769319085340260noreply@blogger.com0tag:blogger.com,1999:blog-445788637623239574.post-1247964070818534952012-11-14T19:20:00.002+08:002012-11-14T19:20:35.985+08:00THE SUPERHETERODYNE BASIC INFORMATION
The superheterodyne uses one or more mixers
to convert an incoming signal, regardless of its frequency, to an identically
modulated signal at some other, constant frequency. The signal frequency can be
heterodyned once, twice, or even three times. Thus, you might hear of a
single-conversion, double-conversion, or triple-conversion superheterodyne
receiver.

Down conversion is often used to allow
reception of ultra-high-frequency (UHF) and microwave signals (above 300 MHz).
The UHF or microwave input is mixed with an LO to provide an output that falls
within the tuning range of a shortwave VHF receiver.

UHF/microwave reception is shown in Fig. 27-11B.

Basics of Grid Computing
Grid Computing harnesses distributed
resources from various institutions (resource providers), to meet the demands
of clients consuming them. Resources from different providers are likely to be
diverse and heterogeneous in their functions (computing, storage, software,

In 1996, the vast majority of domestic amplifiers were two-channel stereo units. Since then there has been a great increase in other formats, particularly in multichannel units having seven or more channels for audio-visual use, and in single-channel amplifiers built into subwoofer loudspeakers.

In commercial practice, this is decided for you by the marketing department. Even if you can please yourself, the power output capability needs careful thought as it has a powerful and non-linear effect on the cost.
