Hallo,
People who use the Signals&Systems package might be able to help me.
I want to design an ordinary RC-lowpass with the DesignAnalogFilter
function.
What's the correct filter specification? I used
Passband[10^(-3/10),{0,wg}],
Stopband[10^(-23/10),{10*wg,Infinity}]
But this doesn't return the correct 3dB at the corner frequency and neither
the correct slope of 20dB/decade.
Where's my error?
