The Fast Fourier Transform allows computers to take complex signals and break them into their underlying frequencies. This ...
Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...
Audio frequency detection is the process of identifying the pitch or dominant frequency of a sound signal. Three common methods used are Fast Fourier Transform (FFT), AutoCorrelation, and ...
Abstract: Massive MIMO (m-MIMO) is crucial for 5G and beyond 5G/6G V2X (vehicle-to-everything) communications due to its ability to cancel interference and enhance performance. However, V2X ...
In part 3 of this series, we used the inverse fast Fourier transform (IFFT) to create 100-Hz time-domain waveforms of various amplitudes and phases. We can also use the IFFT to create waveforms ...
