What is the frequency ratio of the output to the input of a single-phase full-wave rectifier?

• A. 1:1
• B. 2:1
• C. 3:1
• D. 4:1

Answer: (B)

In a single-phase full-wave rectifier, the output frequency is effectively doubled compared to the input frequency. This is due to the rectification process, where both halves of the AC waveform are utilized to produce a pulsating DC output. For a standard alternating current (AC) input signal with a frequency of \( f \), the full-wave rectifier generates an output frequency of \( 2f \). Therefore, the frequency ratio of the output to the input is 2:1, indicating that for every cycle of input, there are two cycles of output in a full-wave rectifier configuration. This doubling of the frequency is a fundamental characteristic of full-wave rectification, making the answer 2:1 accurate in describing the relationship between output and input frequencies.
