A PCM-Based Vocoder/Decoder, a voice codec software based on PCM of voice signals to send over data network, whose quantizer provides both mid-rise and mid-tread quantization techniques, and an ...

Conclusion: Pulse Width Modulation Simplifies Power Delivery When PWM is used as a DAC to generate analog waveforms, a reconstruction filter as shown in Figure 1a is required, and the filtered ...

PDM — pulse density modulation — is similar to PWM and, like PWM, requires a filter that could range from a simple RC network to an active filter. You can see the result in the video below.

Emerging systems such as Internet-of-things (IoT) and machine-to-machine (M2M) communications have strict requirements on the power consumption of used equipments and associated complexity in the ...

This code example shows how to use a digital microphone with the PDM/PCM block. It measures the sound intensity (volume), and turns ON an LED when the volume exceeds a threshold. You can reset the ...

In some applications, throttling of the manipulated flows is difficult or impossible. In the biochemical industry, where precise (good resolution and sensitivity) throttling valves without any ...
