Bessel Filter Prototype Element Values
Gaussian filter is a filter whose impulse response is a Gaussian function. Gaussian filters are designed to give
no overshoot to a step function input while minimizing the rise and fall time. This behavior is closely connected
to the fact that the Gaussian filter has the minimum possible group delay. Mathematically, a Gaussian filter
modifies the input signal by convolution with a Gaussian function; this transformation is also known as the
The table below lists prototype element values for the
normalized lowpass function, which assumes a cutoff frequency of 1 rad/sec and source and load impedances of 1 Ω.
Either an input capacitor (top reference line in table) or an input inductor (bottom line in table) can be used.
Convert values to other cutoff frequencies, impedances, and to highpass, bandpass or bandstop using the
