What is meant by pulse amplitude modulation?
Pulse amplitude modulation (PAM) is the transmission of data by varying the amplitude s ( voltage or power levels) of the individual pulses in a regularly timed sequence of electrical or electromagnetic pulses.
What is the basic principle of PAM?
The PAM fluorometry principle is based on a 1 μs pulse of light (low intensity, non-actinic) that is synchronized to a lock-in amplifier. This allows effective quantum yield determinations to be performed in (sun) light, as the lock-in amplifier removes all signal not associated with the lock-in signal.
What is Pulse Position Modulation PDF?
Pulse Position Modulation (PPM) is an analog modulating scheme in which the amplitude and width of the pulses are kept constant, while the position of each pulse, with reference to the position of a reference pulse varies according to the instantaneous sampled value of the message signal.
Why is pulse amplitude modulation used?
Answer 1: Pulse Amplitude Modulation helps in the transmission of analog signals through Pulse Stream. Moreover, this enables easy conversion of analog signals into digital ones.
