Tracking a sine wave with noise
That's actually not a trivial problem and the best approach really depends on your specific requirements.
My first approach would be a phase-locked loop and simply use the local oscillator as the pr …

How to specify the cut-off frequence in cascaded biquad filters?
Do we just cleverly set the $a_{1,2}$ and $b_{0,1,2}$ coefficents?
Yes.
The coefficients determine entirely what he filter does: shape (lowpass, highpass, bandpass, peaking EQ, shelve, etc.), steepn …

converting complex sum of exponential signal to real signal
For what values of the model parameters, does it generate a real signal?
That's probably not possible. Roughly speaking, your frequencies are all positive and a real signal must have a conjugate sym …

Estimate Sine Frequency under White Noise — simple and effective method
This depends on the precision needed.
If it's a pure sine wave that's noise free, you can get a very quick estimate by measuring the difference between two zero crossings.
The tricky part is that most …
