1. High pass filter 1.1. Purpose Filter a signal with a high pass filter. 1.2. Description See Low pass filter for a description of the method. For a given signal \(x(t)\), the high pass filtered signal is \(x_{HP}(t) = x(t) - x_{LP}(t)\). 1.3. Input Any equidistant signal (see Signal Types ). The cut-off frequency, the number of coefficients and the tapering exponent are given as input in the editor. 1.4. Output High pass filtered signals. Band Pass Filter Low Pass Filter
