What is Signal Generator?: What is Signal Generator? : A signal generator is a vital component in a test setup, and in electronic troubleshooting and development, whether on a service bench or in a research…
Wideband Antenna Types: It is often desirable to have an antenna capable of operating over a wide frequency range. This may occur because a number of widely spaced channels are used, as in short-wave transmission…
Classification of Pulse Signals: The Classification of Pulse Signals are divided into four categories, namely Periodic signals. Aperiodic signals. Random signals. Continuous and Discrete Signals 1. Periodic Signals: Periodic signals are those which repeat themselves…
Classification of Amplifiers: In the Classification of Amplifiers, the transistor amplifiers may be classified in several ways such as on the basis of transistor configuration used, active device used, output, frequency range of operation, input,…
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.…
Voltage Stability in Power System: Voltage Stability in Power System - Voltage control and stability problems are very much familiar to the electric utility industry but are now receiving special attention by every power system…
Effect of Internal Transistor Capacitance: As we know already that at high frequencies, the coupling and bypass capacitors act as short circuit due to their low reactance and hence the voltage gain is not affected.…
Transistor Datasheet: To select a transistor for a particular application, the Transistor Datasheet provided by device manufacturers must be consulted. Most data sheets start off with the device type number at the top of the…
Frequency Response of RC Coupled Amplifier: The curve drawn between the voltage gain and signal frequency of an amplifier is known as the frequency response. The performance of an frequency response of RC coupled amplifier…
Fiber Optics History: Fiber Optics History - In 1870 John Tyndall, a natural philosopher living in England, demonstrated one of the first guided light systems to the Royal Society. His experiment involved using water as…
