What should the frequency of the PWM signal be? First, consider the case where we are using the PWM signal as a D/A converter. A wide variety of microcontroller applications exist that need analog ...

A pulse signal is defined by its amplitude and pulse width.A periodic pulse train has a frequency, or pulse-repetitionrate, and a duty cycle—the ratio of pulse width to repetitionperiod, varying ...

In summary, pulse code modulation involves sampling the analog signal, quantizing the value of the sample, and creating a fixed bit length digital word for each digitized sample. IT’S IN THE CODING ...

A North American telephony standard for converting analog voice into a digital data stream using pulse code modulation (PCM). The "pulse code" in PCM comes from the telephone company's method of ...

The audio data on the CD is in the form of PCM, or pulse code modulation. In PCM, the amplitude of the analog audio waveform is sampled periodically, and the samples are quantized: Each sample is ...
