Assuming a capacitor, C value for both filter sections (CLP, CHP) of 0.2uF, calculate the values of
the two resistors, RLP and RHP using the formula:
1. From the Low pass filter formula, Find RLP:

2nRLpCLP
2. From the High pass filter formula, Find RHP:

2nRHp CHP
3. Calculate the center frequency (f) and Bandwidth (BW):
a. fc = Vfi x fu
b. BW = f# - f.

The transformation of this filter characteristic can be easily implemented using a single low pass
and high pass filter circuits isolated from each other by non-inverting voltage follower, (Av = 1).
The output from these two filter circuits is then summed using a third operational amplifier
connected as a voltage summer (adder) as shown in Figure 1.
