D 1.78 An amplifier with an input resistance of 100 kΩ and an output resistance of 1 kΩ is to be capacitively coupled to a 10- kΩ source and a 1- kΩ load. Available capacitors have values only of the form 1 × 10−n F. What are the values of the smallest capacitors needed to ensure that the corner frequency associated with each is less than 100 Hz? What actual corner frequencies result? For the situation in which the basic amplifier has an open-circuit voltage gain (Avo) of 100 V/V, find an expression for T(s) = Vo(s)/Vs(s).
