Thank you for your response, I got your point. But I need to know this:
I want to receive a GPS L1 signal (1575.42MHz) and I studied that the local
oscillator of RTL-SDR has the intermediate frequency of 3.57MHz-4.57MHz. So
when the signal with this IF goes to ADC of SDR, I want my ADC to sample
this incoming signal at a sampling rate of 38.192MHz (as per the
requirement). But when I try to put this sample rate in RTL-SDR, it starts
dropping samples. I want to know that is there anything am I doing wrong OR
it is the limitation of my RTL-SDR.
