Hello, I am using ADS1298. When I conect an input signal it appears a multiplicative modulated noise in the output.
When I do the FFT on matlab it appears the noise components around 50 Hz, 100 Hz, 150 Hz.... Like an AM modulation...
What could be the reason of this?
I show you the pictures :
This is the FFT when my input signal is a 8Hz 100mVpp from the signal generator
and this is the same signal in time domain:
Please help me.
Thank you very much.
