6 dB Gain Low-Pass
A low-pass filter with 6 dB of gain is shown in Figure 2. The transfer function for this filter is given by Equation (1) where
Figure 2: Low-pass filter with 6 dB gain.
By backward-solving and substitution, the following set of equations results:
Substituting for the coefficients as before, the resistor solutions are as follows:
Let M= ? 2+ ?2
