I want to sample a periodic sinusoidal signal ranging from 40Hz up to 5Mhz,
I need to sample at least 10 samples per cycle so the sampling frequency should be at least 50Mhz if doing a continuous sampling.
For you information I am using the PIC18f4550 which is a slow microcontroller and I want to prevent from changing it, also I can have a reference signal that is at the same frequency of the sampled signal.
My question is: Is there any techniques for sampling a high frequency periodic signal?
Or is there any high speed ADCs (10bits up to 16bits) with a programmable sampling frequency and an internal buffer memory that I can read it after taking the samples?
