a) A typical treble tone-control circuit, providing both treble "boost" and "cut;" is shown in the figure on the next page. Sketch the magnitude of the frequency response of this circuit for the three positions of the potentiometer shown in (1), (2), and (3). Make reasonable approximations.

b) Discuss the "taper" of the potentiometer-the curve of resistance between the tap and one end as a function of geometric tap position or shaft angle-that would probably be appropriate for this circuit. (With the addition of several more elements this circuit can provide both treble and bass control as shown below.)
