Theory of Frequency Modulation and Phase Modulation: Frequency Modulation and Phase Modulation is a system in which the amplitude of the modulated carrier is kept constant, while its frequency and…
Extensions of Single Sideband Amplitude Modulation: The Extensions of Single Sideband Amplitude Modulation is namely, Forms of Amplitude Modulation: This section on amplitude modulation defines, describes and lists the main applications…
Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates…
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…
Microprocessor Programming: A program is a set of instructions arranged in the specific sequence to do the specific task. It tells the microprocessor what it has to do. The process…
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…
Voltmeters and Multimeters Articles: DC Meter: The most commonly used dc meter is based on the fundamental principle of the motor. The motor action is produced by the flow of…
