Hey everyone,

So I have this question:
In a certain application an output signal with f=500 Hz is affected by a DC offset and a 400 KHz noise signal. Design, Simulate and implement a circuit that will cancel the offset and attenuate the noise signal by around 20 dB.

Shall I design first a low pass filter or a bandpass filter. Because I need a LPF to pass the 500 and attenuate the 400K, then I need the HPF to reduce the dc offset. Also, how can I determine the values of the R and C?

Thanks a lot in advance.
