For the circuit in Fig. 16.18, sketch a typical waveform that would occur on the node connecting , , and when the code signal, , goes low-to-high and high-to-low. Assume here that the code signal has a logic swing of 0 to 5 V, that the threshold voltage for the transistors equals –1 V, and that is 1 V.
