How do you find the frequency of a content?

If x is an point segment of , one way to determine its frequency content is to take its discrete Fourier transform (DFT) by using the fast Fourier transform (FFT) to compute it: >> X=fft(x); This gives us an component vector , which in general will be complex valued.

What is uniformly sampled signal?

• Uniform sampling. – The spectrum of uniformly spaced samples is also a set. of uniformly spaced spikes. – Multiplying the signal by the sampling pattern. corresponds to placing a copy of the spectrum at each.

What is non uniform data?

Non-uniform sampling technique generates fewer samples, which means less data to process and lower power consumption. Furthermore, asynchronous logic is known to be data-driven. It proves to be more adapted to the non-uniform sampling than synchronous logic.
