Thanks.I am doing 4096 pt FFT. Hence the resolution is 625000/4096. The cut off frequency is 25 KHz and the passband and stopband ripples were 0.1dB.
Thanks.I was trying to write the C++ program to read the signal from sound card, down converting it to IQ. Hence, looking for equivalent of fir2.
Thanks.Basically, I was experimenting LPF design using custom design. So, that if I have to add a notch, I can combine it in a single filter rather than convolving...
Thanks for response.Yes, I have considered both +ve and -ve part of amplitude spectrum. I have got the real series after inverse FFT
I am trying to design the Blackman Window based FIR Low Pass Filter (as described in http://www.dspguide.com/CH17.PDF) for the IQ signal having sampling rate of...
I am very new for receiver design. What is IF Flatness and RF levelling? Are these achieved in signal processing or at RF level.Thanks to one and all.RegardsGaurav...
