Rotating Magnetic Field: Rotating Magnetic Field - It was seen earlier that the sinusoidal current in any phase of an ac winding produces a pulsating mmf wave in space whose amplitude varies sinusoidally with time.…
Reactive Plasma Etching: The reactive plasma is the discharge in which gases ionized producing chemically active species, oxidizers, reagents. The plasma is reactive in both gaseous and solid phase, hence the name is Reactive Plasma.…
Single Sideband Modulation (SSB): Single Sideband Modulation (SSB) can he obtained by passing the output of a carrier suppressor (product modulator) through filter circuits that are selective to transmit one sideband while suppressing the other.…
Radio Frequency Modulation: Radio Frequency Modulation - The simplest method of measuring frequency deviation utilises an FM receiver with a BFO as the measuring instrument. The only coupling used is the air waves between the…
Introduction to State Estimation in Power System: Introduction to State Estimation in Power System plays a very important role in the monitoring and control of modem power systems. As in case of load flow analysis,…
Pulse and Square Wave Generator Block Diagram (Laboratory Type): Pulse and Square Wave Generator are used as measuring devices in combination with a CRO. They provide both quantitative and qualitative information of the system under…
Transformer Coupled Class A Power Amplifier: Transformer Coupled Class A Power Amplifier also sometimes referred to as single ended power amplifier. The term "single ended" (denoting only one transistor) is used to distinguish it from…
Double Cage Rotor Induction Motor: A rotor design, which though more expensive gives still better starting, and running performances than the deep-bar design, is the Double Cage Rotor Induction Motor. The double squirrel cage induction…
FET Common Source Amplifier with Unbypassed Source Resistors: Equivalent Circuit - When an unbypassed source resistor (RS) is present in a FET Common Source Amplifier circuit, as shown in Fig.11-10(a), it also appears in the…
Coupling and Bypassing Capacitors: Coupling Capacitors - To use a transistor circuit to amplify or otherwise process an ac signal, the signal source must be connected to the circuit input. If the source is directly…
