Fourier Transformation Exam Questions and Answers Discrete Fourier Transform - Answer-All our data is digital and the FT works on analog. So we need a discrete formation of the FT Discrete Fourier Transform (DFT) - Answer-1)Assumes regularly spaced data values 2)Returns the value of the fourier transform for a set of values in frequency space which are equally spaced Matlab Functions - Answer-fft(X) fft2(X) fftn(X) Phase Spectrum = angle(fft(X,N)) Linear Operator - Answer-If f(X...

What frequency should you save at for a recording? - sample at twice the rate of the highest frequency in the signal, data up to 100 Hz should be sampled at 200 Hz What is Nyquist? - is half the sample rate (the highest frequency you can reproduce) What is quantization - the process of converting a voltage, which is analog, into a number, which is digital (it creates a number that reflects a signal amplitude, one number is a 'snap shot') What is a sampling rate? - is how often you...

data are processed by making certain assumptions about the underlying function. This motivates an alternative formulation of the NAC goal involving integrals of A(z) that render the problem well-defined. With additional assumptions about the smoothness and other properties of A(z) behind these integrals, consistent with both a priori and a posteriori knowledge, the ambiguity of the solution can be substantially suppressed. The simplest setup is as follows: Given a set of finite interval...
