To All from PA0SEDoes someone know whether a DSP filter using the sound card of the computer can be found on the internet , that can filter the audio output of the receiver with an adjustable bandwidth down to, say, 20Hz or so? I use a passive audiofilter between the receiver and the headphones with four tuned circuits. It has a bandwidth of about 25Hz, a centre frequency of 900Hz and a linear phase characteristic to avoid ringing. But perhaps a DSP filter could do even better. 73, Dick, PA0SE JO22GD |
