Okay this blog is wrong. The freq domain representation of an impulse is not sinusoidal. The spectrum of an impulse is spread continuously over a broad frequency range. Maybe the author was playing with an FFT library that they just didn't understand properly.
- zeroxfe 7y agoYou're talking about the magnitude, which is spread evenly across the frequency range. The real component of the freq domain representation is in fact sinusoidal. Time-Frequency duality is a well-known phenomenon in signal processing. > Maybe the author was playing with an FFT library that they just didn't understand properly. There's no need for that.
