Decibels and Half Power Point Method: Power Measurement in Decibels and Half Power Point Method - The power gain (Ap) of an amplifier may be expressed in terms of the…
Transistor Construction Techniques and Performance: The following are Transistor Construction Techniques and Performance are as follows, Current Gain: Good current gain requires that most charge carriers from the emitter pass…
Color Television Receiver Block Diagram: Figure 17-25 shows the block diagram of a Color Television Receiver Block Diagram, but for simplicity the circuits shown in Figure 17-23 are omitted. Interconnection…
Color TV Transmission and Reception: If color TV had come before monochrome TV, the system would be far simpler than it actually is now. Since only the three additive primary…
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…
Microwave Transistors: Silicon bipolar transistors were first on the microwave scene, followed by GaAs field-effect transistors. Indeed, FETs now have noticeably lower noise figures, and in the C band and…
Phase Discriminator: This Phase Discriminator is also known as the center-tuned discriminator or the Foster-Seeley discriminator, after its inventors. It is possible to obtain the same S-shaped response curve from…
