DC Load Line of BJT Biasing Circuit: The DC Load Line of BJT Biasing Circuit is a straight line drawn on the transistor output characteristics. For a common-emitter (CE) circuit,…
Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
Parametric Amplifier: The parametric amplifier uses a device whose reactance is varied in such a manner that amplification results. It is low-noise because no resistance need be involved in the…
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…
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…
Transistor RF Amplifier Circuit: A radio receiver always has an RF section, which is a tunable circuit connected to the antenna terminals. It is there to select the wanted frequency…
Speed Control of DC Motor: The Fig. 15.38 shows the analog approach to control the Speed Control of DC Motor. A tachometer is used to get the information about the…
ADC0808 Pin Diagram: The ADC0808 Pin Diagram and ADC 0809 are monolithic CMOS devices with an 8-channel multiplexer. These devices are also designed to operate from common microprocessor control buses,…
