A rejection network that can be used instead of the twin-T network of Example 8.4 is the bridged-T network shown in Figure P8.3. The transfer function of this network is
(a) Determine the pole-zero pattern and, using the vector approach, evaluate the approximate frequency response, (b) Compare the frequency response of the twin-T and bridged-T networks when Q = 10.
Example 8.4
As an example of the determination of the frequency response using the pole-zero diagram and the vectors to jω, consider the twin-T network shown in Figure 8.14 [6]. The transfer function of this network is
