Hello everyone,
I'am building an FM transmitter in gnuradio .Well the audio wave file is connected to wbfm transmitter through resampler block.The audio sample rate is 48KHZ and according to the wbfm block the quadrature rate and audio rate are related by mod function (quad_rate % audio_rate=0) so i'm setting the output sample rate to the multiplies of 48 but when i set the audio rate and quad rate equal i'm able listen properly to the transmitted audio file.If it is set to different values i'm hearing alot of noise and sometimes samples running very fast or very slow
