hi all:
        There are two C++ files rcvLPF_651.h and sendLPF_961.h in the Transceiver folder. I think it is the coefficients of the LPF which is used in the process of changing the sample rate.  But what I want to know is how these coefficients are been calculated. Have it already considered the value of the interpolation and decimation in the process of calculating? Besides, why the numbers of the taps of the LPF is 651 in the send side and 961 in the receive side?
