摘要：

In this paper we design, simulate, build an active adjustable band-pass filter that is connected to a portable audio device such as an mp3 player or laptop. The low pass filter has an adjustable bass, the high-pass filter has an adjustable treble, and the overall system has a volume control. By combining with a low-pass filter, a high-pass filter, a band-pass filter and a summing amplifier the system achieves adjustable pass band, volume and both treble and bass control.
