A black screen on your computer can mean several things. A black screen is most commonly a screen saver, but there are other possibilities. My computer switches to a black screen after about 5 to 15 minutes of use. Then I have to turn it off to get another 5 to 15 minutes of use.
Time and frequency domain for the same signal. A fast Fourier transform (FFT) algorithm computes the discrete Fourier transform (DFT) of a sequence, or its inverse. Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa.ime and frequency domain for the same signal.
