Topic: Analog Circuits
In this circuit, V is a sinusoid input with frequency f, current i contains
- A. Only f
- B. All harmonics of f
- C. Only even harmonics of f
- D. Only odd harmonics of f
Answer: B. All harmonics of f
Explanation: Here, the two diodes are in parallel and connected in opposite directions. So, for positive half cycle, diode $D_{1}$ will allow the voltage to flow. For negative half cycle, diode $D_{2}$ will allow the voltage. Thus, current i contains all harmonics of f.
