Questions 1-3 below are about the amplifier circuit of Figure 1. Here Vcc is a fixed voltage The base voltage vB(t) is time-varying, and is of the form vB(t) V(t) where VB is a DC offset, and vb(t) is a time-varying purely AC signal. Suppose the amplitude of vb is A. Assume that the capacitor C is...
