WebWith the high-pass filter, increasing the frequency will slightly raise the output, while decreasing the frequency will drastically decrease the output. The low-pass will … WebMar 17, 2024 · An anti-aliasing filter is just a low pass filterwith the cutoff frequency (i.e., the -3 dB frequency) set to the Nyquist frequency. This filter cuts out any higher order frequency content in the input signal as any frequencies higher than the Nyquist frequency would be aliased.
