Hi All, I have a question, which is probably DSP 101 basics, but I just wasn't 100% sure.
If I am applying a 1024 point FFT to a continuous time-stream from an ADC with sampling ~ 1 GSPS, I will have a time resolution ~ 1 microsecond (and frequency res. of ~ 1 MHz). But, if I instead apply an 8 tap PFB, am I essentially smearing out my time resolution by a factor of 8, since I am now summing 8 rows of my 1024 point time streams? I can't see how the number of PFB taps wouldn't affect my time resolution. Or am I missing something?
