What is another word for pulse modulation?
Pronunciation: [pˈʌls mˌɒdjʊlˈe͡ɪʃən] (IPA) 
Pulse modulation is a technique used to convert analog signals into digital signals. There are several synonyms for this term, including pulse-code modulation, pulse duration modulation, pulse position modulation, and pulse amplitude modulation. Each of these techniques involves altering one or more of the pulse characteristics to represent the analog signal. Pulse-code modulation involves converting the signal into a stream of binary numbers. Pulse duration modulation varies the duration of the pulses to represent the signal. Pulse position modulation changes the position of the pulse within a fixed period, while pulse amplitude modulation alters the amplitude of the pulses. All of these techniques are used in different applications to process analog signals.
