What is Low Frequency Compensation? The coupling or blocking capacitor tilts the amplifier response for step input. In Fig. 16.28, if a high value of resistance Rd is added in…
FET as a Voltage Variable Resistor (VVR): FET is a device that is usually operated in the constant-current portion of its output characteristics. But if it is operated in the…
Tunnel Diode Applications: In all its Tunnel Diode Applications, the tunnel diode should be loosely coupled to its tuned circuit. With lumped components, this is done by means of a…
Tuned Radio Frequency Receiver: The Tuned Radio Frequency Receiver is a simple "logical" receiver. A person with just a little knowledge of communications would probably expect all radio receivers to…
Heterodyne Wave Analyzer: Wave analyzers are useful for measurement in the audio frequency range only. For measurements in the RF range and above (MHz range), an ordinary wave analyzer cannot…
Radio Communication System - Block Diagram and types: Radio communication is very popular technique of communicating a message. The radio waves are electromagnetic waves produced due to escape of electrical…
Methods of Suppressing Unwanted Sidebands: As stated earlier, the three practical methods of SSB generation all use the balanced modulator to suppress the carrier, but each uses a different method…
