Hello, I am a student doing research in high-speed electrical link. I have came up with a new signaling scheme, and want to see spectrum plot of it but not sure how to correctly perform fft on the signal in matlab. My signaling scheme, uses phase modulation to have same spectral efficiency as PAM-4 signal (which is 2bits/UI) but has one-UI tha

What is the power magnitude in FFT?. Learn more about fft magnitude power ... MATLAB additionally scales all the frequencies except 0 and the Nyquist by 2 in a one ...
One of these environments is provided by the MATLAB®software. MATLAB fulfills the requirements that are necessary to meet and overcome the challenges. In addition—and partly for these reasons—MATLAB has become the de facto standard of scientific computing in our field.
Fourier transform can be generalized to higher dimensions. For example, many signals are functions of 2D space defined over an x-y plane. Two-dimensional Fourier transform also has four different forms depending on whether the 2D signal is periodic and discrete. Aperiodic, continuous signal, continuous, aperiodic spectrum

A tone grows in dB as FFT size increases. As in a true PSD the tone is a Dirac's delta for NFFT->inf. Larger NFFT means smaller dF, and larger A, in such a way that A * dF = constant; A unit power noise stays at 0dB. This is really a [Watt/Hz] spectral density and total power given by:
I have measurements of time and current which were made with a digital oscilloscope. When I import them in MATLAB and plot them my sinewave is pretty much like my the waveform I saw in the oscilloscope and in the excel file (time domain).
