WebApr 11, 2024 · Sine wave input signals always produced a higher RMSE than bandlimited noise, resulting in lower f 40 values. Depending on the interpolation method, the required OSR was between 5% and 8% higher for sine waves, which were therefore considered as the worst-case scenario and used as standard input signals in the following tests. WebThe Python example creates two sine waves and they are added together to create one signal. When the Fourier transform is applied to the resultant signal it provides the frequency components present in the sine wave. # …
