WebIn signal processing, a filter is a device or process that removes some unwanted components or features from a signal. Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal. Most often, this means removing some frequencies or frequency bands. WebThe design steps to select the inductor and capacitor values for the input filter are discussed further.

For a FIR, I've seen in Harris' windowing paper that the DC gain is the sum of the filter weights. G = ∑ i = 0 N − 1 w i. For a FIR, I've seen that the noise gain is the square root of the sum of the square of the weights. G = ( ∑ k = 0 N − 1 w i 2) 1 2. graham cracker brickle
