hi All,
I have a question about filtering a signal using fir filters.
I am tring to filter a qam signal with a root raised cosine pulsee shape filter and my filter have two inputs bit and 15 output bits. After the filter I have a DAC with a 10 bits resolution.
How have I to choose in the right manner the filter output bits to connect to the dac?
If the simbol rate is 10 MHz what have to be the frequency clock for the filter using a distribuited arithmetic parallel filter?
Is the right choice to have a filter with two input bits instead of two separate filters with 1 input bit?
Tx a lot.
