Pulse Code Modulation(PCM): Pulse Code Modulation(PCM) is different from the other forms of pulse modulation studied so far, PCM also uses sampling techniques, but it differs from the others in…
Pulse Position Modulation(PPM): In this Pulse Position Modulation system, the amplitude and width of pulses is kept constant, while the position of each pulse, in relation to the position of…
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 Time Modulation(PTM): In Pulse Time Modulation the signal is sampled in the same way as in PAM, but the pulses indicating instantaneous sample amplitudes have a constant amplitude themselves.…
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.…
