To learn about the design of
communications circuits. In other courses, the block diagram
approach has been used but in this course the emphasis will be
on the actual circuitry which makes up these blocks. Examples
of such blocks are tuned amplifiers, mixers, oscillators, phase
shifters and detectors. Communications systems considered are
AM, FM, television and telephony. Use of the PLL will be discussed.
Course Content
Introduction to Telecommunications:
Components of a radio systems; noise, distortion impedance matching.
Mixers and Modulators:
Phase-Locked Loop and Applications:
Introduction to PLLs and applications such as:
synthesizers and FM demodulation.
Oscillators:
Frequency modulators and demodulators:
Television Systems:
Transmission of intensity, color, retrace, blanking, and sound;
generation of the video signal, conversion of the video signal
to picture and sound. Other topics may include high-definition
TV, stereo sound.
Labs
Simulation Labs - Groups of 1; Hardware Labs - Groups of 2, one
writeup per group, due one week after the scheduled lab day, 4:30 PM.
Tuned Amplifiers: (Dates removed, these were 2000)
(September ??, ??, ??). Simulation Lab. Use
of a bipolar transistor and some passive components to build
a tuned amplifier operating at about 1MHz. You will learn about
use of transistor parameters, tuned circuits and impedance matching.
Mixers and Modulators:
(October ??, ??, ??) Use of an analog multiplier on an IC to
build frequency changers.
Phase-Locked Loops:
(November ??, ??, ?? and ??, ??, ??) Use of a commercially available
package to build a tracking filter, a synthesizer and a an FM
demodulator. The IC contains a voltage-controlled oscillator
a phase detector, and amplifiers. In this lab, the VCO and phase
detector will be characterized, then a complete phased-lock loop
will be built. The main external components will consist of a
simple loop filter and a divider to realize the synthesizer.
Marks:
a) Three assignments worth 5% each
b) Three Labs worth 10, 10,15 (about 1/3 for demo)
c) One written exam worth 50%.
**** Students must get at least 35% in the final exam. ****
Text:
There is no official course text. The printed course notes should
provide enough material, or some of the references can be consulted.
