摘要
低频功率放大器在现代生活中被广泛应用.在扩声中起着极其重要的作用,是各类音响器材中最大的一个家族.本文设计的低频功率放大器,由五部分组成,满足了输出功率,频率通带,失真度和效率的要求.
The low frequency power amplifier is common in modern life.It is playing extremely important role in loudspeaker,and it is a maximal clan of all kinds of audio equipment and material.The design of the low frequency power amplifier has satisfied the request such as the output power,frequency belt,distortion degree,efficiency.With the rise of engineering level,low frequency power amplifier function was improved step by step,the figure power amplifier readjusts oneself to a certain extent to replace the amplifier simulating power step by step.
