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 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…
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…
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.…
Beat Frequency Oscillator (BFO) | Block Diagram | Working and Limitations: In this Beat Frequency Oscillator, the outputs of two RF oscillators are applied to a square law detector and…
Digital Frequency Meter: Principle of Operation of Digital Frequency Meter - The signal waveform is converted to trigger pulses and applied continuously to an AND gate, as shown in Fig.…
What is Sinusoidal Pulse Width Modulation?: In Sinusoidal Pulse Width Modulation the pulse-width instead of being uniform as in the waveform of Fig. 11.55 is a sinusoidal function of its…
Electronics Engineering Multiple Choice Questions and Answers (MCQs) Part 3: 106. Which of the transistor models is most preferred for the analysis of a transistor circuit both at mid-band and…
