Amplifier circuit design
- Mar 20, 2018 -

Many places (such as shopping malls, schools, stations, stadiums, etc.) are equipped with a broadcasting system. Its main function is to play music, broadcast notices and news. These broadcast systems all contain sound amplification equipment to amplify weak signals sent from microphones, cassette decks, and CD players into high-power signals that can drive speaker sound. According to actual needs and amplifier parts, there are many types of sound reinforcement circuit design. As the design of the electronic circuit, the performance of the sound reinforcement circuit proposed by this subject is relatively low, and the operational amplification integrated circuit and the audio power amplification integrated circuit introduced in the theoretical subject are mainly used to constitute a sound reinforcement circuit. The loudspeaker with low performance index is mainly due to its low price, simple production, and does not require too many expensive integrated blocks.
