Calculate the actual frequency of circuit, Electrical Engineering

(a) The circuit of Figure 1 represents an amplifier-speaker connection. The filter is a low pass filter which is connected to the woofer. The filter is a -network.

(i) Design a constant-k π low pass filter with a cut-off frequency of 15 kHz and terminated with a resistive load of 600[1].

(ii) Draw the circuit diagram indicating the component values and hence sketch the circuit response, showing it mimics a Butterworth filter response.

(b) Using the table of Normalised values (and indicate the values selected), design a passive 3rd order Chebyshev Low Pass filter, with a cut-off frequency of 15 kHz and a design impedance of 600[1]. The ripple in the pass band is not to exceed 3 dB. Draw the circuit diagram, and show the component values. Sketch the frequency response expected.

(c) By simulating the circuits or otherwise, compare the actual frequency response of the filters of (a) and (b).
