Investigate Spikes in Noise Spectrum

[tamerakassie]

The noise spectrum plot shows some spikes that are not well understood, we chose a 'clean' frequency band and we still notice spikes. This could be a result of firing the noise diodes, and since we are working with uncalibrated data we could be seeing these spikes that have not been corrected for at this stage. We should start with the following for this check:

1. Investigate if the spikes are present across the frequency bands. Apply a cut-off for the spikes, i.e 2*std above the mean noise, and check if there are other spikes across the other channels.
2. Plot the theoretical noise from the radiometer equation.
