DSP decimation/interpolation question

  1. Nov 5, 2017 #1
    I am new to DSP. Say I have a network system receiving and transmitting data. I would be using polyphase decimation at the beginning of the receive path and poly-phase interpolation at the end of the transmit path. Do the interpolation and decimation length needs to be the same? i.e. Will this cause any issues with the filterstates on the data if the input lengths were different than the interpolation? If so what are the issues?
