Remove noise from detector signal to allow accurate area calculation of a section of the curve
I can provide a clear direction, but it is going to be a lot of work given the confession of no background in signal processing, MATLAB or Python. If you are prepared to roll up your sleaves, this ...

What happens to output signal if the filter has a large time delay
We would not expect to see zeros at the output of an FIR filter since the output at any time for an FIR filter is the weighted samples of the current input and the past $N-1$ inputs, where $N$ is the ...

Discrete-Fourier transform of $$u[-n+2]$$
First of all, you're mixing $\mathcal{Z}$-transform and discrete-time Fourier transform (DTFT) here. Just because
$$\mathcal{Z}\big\{u[n]\big\}=\frac{1}{1-z^{-1}}\tag{1}$$
doesn't mean that
$$\textrm{...

High Precision Measurement of Both Magnitude and Phase of Intermodulation Products
My approach to this is as follows (just due to both its simplicity, high accuracy and applicability to the measurement of any tones regardless of sampling rate and frequency relations):
Yes use ...

Communication Channel under Doppler effect
A $\mathbf h$ that gets convolved with the transmitted signal cannot include the Doppler shift; for convolution to be sufficient to model the channel, the channel needs to be LTI (Linearly, Time ...
