Re: 'Phase drift' if oscillator doesn't go through full 360 deg rotation when mixing FIR to bandpass
Hi Rick,Thanks for the reference. It appears we may have to buy that book as the valid pages are blanked out by google, still - good to know that it is out there!It...
Re: 'Phase drift' if oscillator doesn't go through full 360 deg rotation when mixing FIR to bandpass
Hi Rick,Thanks - no problem I just wanted to clarify that they were indeed the same. Do you have any references I could look at to learn about /learn how to implement...
Re: 'Phase drift' if oscillator doesn't go through full 360 deg rotation when mixing FIR to bandpass
Hi,Thank you for the correction. I'm still waiting to hear from some people about why they thought an unknown incoming phase would be a problem. As you say, it shouldn't...
Re: 'Phase drift' if oscillator doesn't go through full 360 deg rotation when mixing FIR to bandpass
Okay... I need to go and do some more digging because now I am under the impression that it is not possible to do this the 'normal' way in our application since...
Re: 'Phase drift' if oscillator doesn't go through full 360 deg rotation when mixing FIR to bandpass
Hi Kaz,Hmmm... I'm sorry I think I got confused for a minute there. It looks like in the colleague's code he had a low pass FIR filter, then he applied the NCO to...
Re: 'Phase drift' if oscillator doesn't go through full 360 deg rotation when mixing FIR to bandpass
Hi Rick,Yes we will be decimating the output of the filter. In our application we will likely be sampling ~5MHz of the 8-20MHz band, and then the final output sample...
Re: 'Phase drift' if oscillator doesn't go through full 360 deg rotation when mixing FIR to bandpass
Hi jmarcelold,So if I understand your post correctly... then the normal way to do this frequency shift and filtering would be to perform the frequency shift on the...
Re: 'Phase drift' if oscillator doesn't go through full 360 deg rotation when mixing FIR to bandpass
Hi kaz,As I understand it, the filter starts out as a low pass, then in order to shift it to a bandpass to get the signal of interest, they multiply it by the desired...
