Of course you can convey many types of information with a PWM signal, but what I mean is that the information conveyed is not in the amplitude of the PWM signal. I think you need to go back and read the whole thread from the beginning. Sushil was asking about generating Audio tones, and complained that the frequency of his generated Audio tone didn't vary, only the "Volume" - ie, amplitude. It was in this context that Steve pointed out that PWM cannot be used to vary the frequency of the generated Audio tone - only its amplitude. You are right to say that the amplitude of the PWM signal itself is constant - but Steve was talking about the generated Audio tone. |
