An engineering project manager has received a proposal from a subordinate who claims the circuit shown in Fig. 1 could be used as a treble volume control circuit if R4 ≫ + R1 + 2RThe subordinate further claims that the voltage transfer function for the circuit is

Where Ro = R1 + R3 + 2R2. Fortunately the project engineer has an electrical engineering undergraduate student as an intern and therefore asks the student to check the subordinate’s claim.

The student is asked to check the behavior of the transfer function as ω → 0; as ω → ∞; and the behavior when ω = ∞ and ß varies between 0 and 1. Based on your testing of the transfer function do you think the circuit could be used as a treble volume control? Explain.
