The problem is I have no idea of the noise characteristics other than it being relatively high (but not quite as high as the expected input) at low frequencies compared to the expected input. We've been asked to design a system that calculates the frequency of the input signal from the sensor...

Okay I have a question involving calculating the FFT of a signal from a sensor. I have simulated many different scenarios in MATLAB of various noise characteristics involving the signal. I want to take the FFT of a noisy signal. As long as my expected input signal has a higher amplitude than...
