I am multiplying a 2kHz sinewave with another 100khz sinewave to obtain
a dsb-sc signal. These sinewaves were designed using DDS cores.
I am also using a 50mHz clock. I would like to demodulate this dsb-sc
signal. I am doing this by multiplying the dsb-sc signal with the
carrier (100khz signal). Now i have to pass this signal through a low
pass filter.
I have generated a coefficient file (.coe) from matlab and am using the
FIR compiler to actually generate the low pass filter.
I have put 50mhz as the input clock frequency but the problem is that i
am not exactly sure what to put in as the sampling frequency. Could
anyone provide some help regarding this.
