What is the output waveform of an unfiltered full-wave rectifier connected to a resistive load?

A full-wave rectifier actively converts both the positive and negative halves of an AC cycle into positive DC. Because a standard AC sine wave goes positive once and negative once per full cycle, rectifying both halves produces two positive pulses for every single incoming AC cycle. Since this output is unfiltered (lacking smoothing capacitors or inductors), it does not form a flat, steady voltage. Instead, it appears as a continuous series of DC pulses. Because two pulses occur per input cycle, the frequency of these pulses is exactly twice the original AC frequency.
