Unformatted text preview: voltage, while full-wave rectifiers convert the entire waveform to dc voltage. Wave-shaping circuits are used to convert the input waveform to some desired output waveform. Clipper circuits cut off the input waveform above and below some max and min specified values, respectively. Clamp circuits offset the waveform in the vertical direction by specifying the peak positive or negative voltage to a specific value. Small signal equivalent circuits can be analyzed to find how input and output voltage ripples are related. In this case, dc sources and coupling capacitors can be replaced by short circuits to solve the circuit for the operating point current, allowing us to model the diode as a resistance. Using the diode resistance with the original circuit and only the ac source, the load output voltage can be found by simple linear circuit techniques....
