Hi guys, im trying to follow and implement the specs of an all digital fm receiver presented in this link:
http://www.ie.u-ryukyu.ac.jp/~wada/design05/spec_e.html
im still making the PLL and i dont know if im doing the right thing.. the output of my loop filter ( the one after the multiplier) is a wave much like the output of the multiplier. I tried having the input and reference signal to be in phase and 180 out of phase and same frequency but the output of the loop filter is still a wave... Shouldn't the loop filter would not allow the high frequency to pass through? Shouldn't the output be just a DC value?
I really need help. thanks.
