Measuring Amplitude Modulation Using CRO: The CRO is widely used as an Measuring Amplitude Modulation. It presents the waveform for visual monitoring and is fairly accurate in measurements of modulation…
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…
Pulse Width Modulation(PWM): Pulse width modulation of PTM is also often called Pulse Duration Modulation (PDM). In this system, shown in Fig. 18.8, we have a fixed amplitude and starting…
Pulse Amplitude Modulation(PAM): Pulse Amplitude Modulation(PAM) is the simplest form of Pulse Modulation. It is shown in Fig. 18.7. PAM is a pulse modulation system in which the signal is…
Pulse Modulation: Pulse modulation may be used to transmit analog information, such as continuous speech or data. It is a system in which continuous waveforms are sampled at regular intervals.…
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…
Modulation Frequency Definition: Modulation Frequency Definition is the process of impressing information on a carrier wave by altering either its amplitude of frequency. In amplitude modulation, the degree is the…
CCIF Intermodulation Distortion: In the second method of carrying out an CCIF Intermodulation Distortion test, the two test signals used have equal amplitude, and relatively high but slightly different frequencies.…
