Experimental questions
1. How to measure the efficiency of the power amplifier in the actual test?
Answer:
To measure the actual output power, an audio signal generator and an audio voltmeter (or oscilloscope, etc.) are required, which are calculated based on the output voltage amplitude under a fixed load.
2. What are the advantages and disadvantages of Class D power amplifiers?
Answer:
Advantage:
The class D power amplifier has a high energy conversion rate, and its size is small, with strong reliability.
Class D power amplifiers can directly realize group control, remote control, monitoring, and other functions without adding any devices.
The class D power amplifier has no relative changes in high frequency, intermediate frequency, and low frequency. Its sound is very clear, and the sound has a very accurate positioning.
Class D power amplifiers can be used in a wide range, and the minimum value of the load impedance connected to it can be very low. In addition, regardless of how the load impedance value changes, the battery conversion rate is basically unchanged.
Disadvantages:
The fidelity of the Class D amplifier is worse than that of Class A and Class B amplifiers
