Re: [Discuss-gnuradio] Pulse on FSK Preamble

Hi Samuel, Is there any reason why you do the quadrature demodulation before the resampler? Usually the CPU limitations require to decimate the signal as soon as possible to a manageable rate for the quadrature demod block. Also, if the FSK symbols are not RC filtered and represent a square wave,

hello Everybody, I am trying to recover my fsk signal with the Muller block. Here is my configuraiton: Sample rate of USRP = 240K bitrate of signal = 9600bps receiving the signal from the USRP, apply a low pass filter -> quadrature demod ->rational resampler -> m sync block My signal contain
