Let's start with the block diagram. A recursive delay consist of forward path, a feedback path, a bulk delay and a feedback gain. There are four different way to arrange these. For each we can derive ...

Is it possible to reconstruct the continuous frequency spectra from DFT/FFT?

Yes it is possible. Add zeros (zero pad) to the time domain samples and then take the DFT. Zero padding the N sample waveform in the time domain out to M samples will provide an M sample DFT with the ...

Finding the right phase offsets for minimizing the highest absolute value of a sum of sinusoids

What you are describing is called a "low crest factor" signal. The crest factor is the ratio of the absolute maximum to it's RMS value. The crest factor is a metric how "peaky" a ...
