PDM — pulse density modulation — is similar to ... PWM was one choice, and some example code uses a timer to do PDM. However, that is not very efficient. The other alternative is to use ...

For example, the 4-bit digital number 0101 equals the decimal ... (If you go through the procedures, the most negative number remains itself.) We’ve now covered pulse code modulation, linear PCM, and ...

[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM ... With a PWM system, for example, if the time period is T, a 50% PWM drive would have the ...
