WebbContinuous-wave (cw) modulation consists of on-off keying of a carrier wave. To recover on-off keyed information, we need a method of detecting the presence or absence of rf oscillations. The CW DEMODULATOR detects the presence of rf oscillations and converts them into a recognizable form. Webb4 juli 2011 · fcfusion said: You're demodulating and filtering using RC components, so it's natural your circuit presents delays t = RC; Solution: use smaller RC values. This will inevitably increase the filter's cut off frequency, lowering the ripple attenuation. Therefore you should also increase the filter's order.
