Time Modulation versus Pulse Width Modulation of a RF (400kHZ) Signal
Time Modulation versus Pulse Width Modulation of a RF (400kHZ) Signal
(OP)
Can anyone share a simple explanation contrasting the two types of RF modulation, or are they the same. Thanks in advance!





RE: Time Modulation versus Pulse Width Modulation of a RF (400kHZ) Signal
There's a Pulse Position Modulation, which is changing the relative timing of a pulse, typically relative to a reference pulse. A bit like ignition advance relative to TDC in a spark ignition engine. Rarely used in radio communications, might be a bit more common in radio navigation.
You can easily Google Pulse Width Modulation or PWM. I assume Wiki would have a good explanation.
Where did 'Time Modulation' come from?
