Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of ...

Figure 4: Pulse Width Density bitstream representation of a sine wave, represented by two bitstreams (red and green) to implement ternary modulation ... sine waves until the wave looks more square ...

Duty cycle is the ratio of pulse width to the signal period expressed as a percentage. Duty factor is the same thing as duty cycle except it is expressed as a decimal, and not as a percentage. If duty ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation.
