Amplitude Modulation Theory: In Amplitude Modulation Theory, the amplitude of a carrier signal is varied by the modulating voltage, whose frequency is invariably lower than that of the carrier. In…
Internal Noise in Communication System: Under the heading of Internal Noise in Communication System, we discuss noise created by any of the active or passive devices found in receivers. Such…
Overvoltage Articles: Simpson Theory of Lightning: The factors that contribute to the formation or accumulation of charge in the clouds are too many and uncertain. But during thunderstorms, positive and…
Measurement of High Voltage and Currents Articles: Series Resistance Microammeter: High d.c. voltages are usually measured by connecting a very high resistance (few hundreds of megaohms) in Series Resistance Microammeter…
Wave Analyzer Articles: What is Wave Analyzer? It can be shown mathematically that any complex waveform is made up of a fundamental and its harmonics. It is often desired to measure…
Measurement Set Up in Electronic Instrumentation Articles: Microwave Power Measurement Techniques: Microwave Power Measurement Techniques can be done by the use of wavemeters. A wavemeter is an adjustable resonant circuit…
Classification of Transmission Lines: Classification of Transmission Lines are usually classified as Lines with no loss or ideal lines, Lines without distortion or distortion less lines Lines with small losses,…
Mathematical Model of Lightning Stroke: During the charge formation process, the cloud may be considered to be a nonÂconductor. Hence, various potentials may be assumed at different parts of the…
