Signal Spectrum Shaping I am looking for methods/algorithms for signal spectrum shaping. Let's say we have a white Gaussian noise and want to have a desired power-spectral density. The first solution that comes to mind is filtering. I was wondering if there are any other techinques.
I appreciate any hints.
but... &quot;shaping the spectrum&quot; is exactly the definition of a filter. I think you can justifiably call everything that shapes a spectrum a filter, so no, nothing but filtering shapes a spectrum.
Note that just because that's the most commonly analyzed case, filters are more than just linear filters.
