Color TV Transmission: Having discussed the manner of indicating luminance and the two components of chrominance in Color TV Transmission, it is now necessary to investigate how they may be,…
Monochrome Television Receiver Block Diagram: Monochrome Television Receiver Block Diagram as shown in Figure 17-9, TV receivers use the superheterodyne principle. There is extensive pulse circuitry, to ensure that the…
Monochrome Television Transmitter: As shown in the block diagram of Figure 17-2, a Monochrome Television Transmitter system is quite unlike any of the transmission systems studied previously. This section will…
Multiplexing in Electronic Communication: Multiplexing in Electronic Communication is the sending of a number of separate signals together, over the same cable or bearer, simultaneously and without interference. There are…
Data Communication Circuit using Modem: Data Communication Circuit using Modem - The name modem is a contraction of the term MOdulator and DEModulator. As the name implies, both functions are…
Stereo FM Multiplex Reception: Assuming there have been no losses or distortion in transmission, the demodulator output in a Stereo FM Multiplex Reception, tuned to a stereo transmission, will be…
Automatic Frequency Control Block Diagram: Automatic frequency control: As previously we see, the heart of an AFC circuit is a frequency-sensitive device, such as the phase discriminator, which produces a…
Intermediate Frequency Amplifier: Choice of frequency: The Intermediate Frequency Amplifier (IF) of a receiving system is usually a compromise, since there are reasons why it should be neither low nor…
