Using the Digital Signal 0 (DS0) encoding, phone calls became digital with an 8 kHz sample rate using 8-bit pulse code modulation, working out to a maximum data rate of 64 kbps per phone line.

Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety of applications, ranging from ...

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

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 ...

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 ...

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 ...
