A standard CW filter operates on the IF (RF after at least one stage of downmixing, but before demodulation). Elecraft's APF operates on the demodulated audio. The reason most filtering is done at IF is because making a nice sharp filter becomes easier the higher the filter's center frequency (within reason). Web.

W9GR: CW note always clear and clean, with no noticeable ringing. On very weak CW there is some high-frequency hiss due to the dithering technique used to reduce 8-bit quantization noise. The state variable filter is composed of the opamps A2, A3 and A4. The potentiometer adjusts the bandwidth of the filter. The potentiometer P2 adjusts the center frequency of the filter from about 200 Hz up to 2 kHz. By setting these two potentiometers correctly, it is possible to filter out a certain frequency band from the entire audio spectrum.

The FT DX 1200 web page says: In the CW mode, the APF (Audio Peak Filter) function has an audio peak at the signal frequency; this improves the S/N and increases the readability of the CW signal. The APF peak frequency can be finely aligned. It works so well that I always have it on when operating CW. I want more details on how it works, though. the easiest solutions is to filter the received audio to only allow a single CW tone to be heard. That's where the Ramsey AF1 filter comes in to help. The audio filter board creates an audio frequency bandpass filter to remove the undesired tones. It also has a selectable bandwidth (the width of the bandpass filter) of 100, 250, 500, or 750 Hz..
