1.31 The connection of a signal source to an associated signal processor or amplifier generally involves some degree of signal loss as measured at the processor or amplifier input. Considering the two signal-source representations shown in Fig. 1.1(a) and (b), provide two sketches showing each signal-source representation connected to the input terminals (and corresponding input resistance) of a signal processor. What signal-processor input resistance will result in 95% of the open-circuit voltage being delivered to the processor? What input resistance will result in 95% of the short-circuit signal current entering the processor?
