FIGURE 18. Half-Wave Rectifier Waveform
The circuit in Figure 17 uses a single supply to half wave rec-
tify a sinusoid centered about ground. R_I limits current into the
amplifier caused by the input voltage exceeding the supply
voltage. Full wave rectification is provided by the circuit in
Figure 19.
