With pulse density, each pulse might be T/10 (as an example) and then the output would be on for 1/10, off for 1/10, on for 1/10 and so on, until by time T you’d still get to 50%.

Abstract: Pulse code modulation (PCM) is being explored as a possible technique for greatly increasing the information handling capacity of conventional telephone cables. For example, there is a ...

The conversion of analogue signals to digital signals therefore eliminates the problems caused by attenuation. Pulse Code Modulation (PCM) is the simplest form of waveform coding. Waveform coding is ...

This example demonstrates how to use the pulse-density modulation (PDM)/pulse-code modulation (PCM) hardware block in PSoC™ 6 MCU with a digital microphone. PSoC™ 6 Wi-Fi Bluetooth® prototyping kit ...

These models use data from pulse-density modulation (PDM) to pulse-code modulation (PCM), which is then sent to the model for detection. The sixth model detects hand gestures uses data from the ...

PDM — pulse density modulation — is similar to PWM and, ... There are several ways [Chris] could produce the output he wanted. PWM was one choice, and some example code uses a timer to do PDM.
