How is the dithering generated and applied for the NCO (numerically controlled oscillator) block in Signal Processing Blockset 6.5 (R2007a)? I would like to know how the dithering …
When using the "kaiser" function in the Signal Processing Toolbox, I find MATLAB to go into a 'Busy' state and remain there indefinitely. Upon some further debugging, I noticed tha…
I am trying to implement a real-time filter so am using MATLAB's butter() function to generate the needed [b,a] vectors [b,a] = butter(4,4/35,'low'); Just to be clear I have used t…
I have been working on code to use the FFT to find the amplitude of a signal. However, despite my best efforts to window I seem to get incorrect amplitudes. When I manually find Am…
