Television Horizontal Deflection Circuit: The function performed by these circuits is exactly the same as already described for the vertical deflection circuits. There are some practical differences. The major one…
Vertical Deflection Circuit in TV: The Vertical Deflection Circuit in TV include the vertical oscillator and amplifier for vertical scanning at 60 Hz and a similar horizontal arrangement for scanning…
TV Video Waveform: Blanking - TV Video Waveform voltage is limited to certain amplitude limits. Thus, for example, the white level corresponds to 12.5 percent (±2.5 percent) modulation of the…
Sawtooth Waveform in Beam Scanning: As previously discussed, one complete frame of a TV picture is scanned 30 times per second, in a manner very similar to reading this page.…
Characteristics of Data Transmission Circuits: Bandwidth Requirements - Characteristics of Data Transmission Circuits is the most instances consists of pulse-type energy. The data stream is similar to a square-wave signal…
Trapatt Diode Construction and Working: The Trapatt Diode Construction and Working is derived from and closely related to the IMPATT diode. Indeed, as pointed out near the beginning of this…
Crossed Field Amplifier: The Crossed Field Amplifier is a microwave power amplifier based on the magnetron and looking very much like it. It is a cross between the TWT and…
