摘要
本文介绍了采用压控电阻、数控电阻、数控电容和运算放大器构成的可控有源全通滤波器电路。该电路不仅具有全通功能,而且实现了增益和相移分别由电压或数字信号进行的独立控制。
This paper presents a design of controllable active all-pass filter employing voltage-controlled resisors, digital-controlled resistors, digi- tal-controlled capacitances and operational amplifiers. The circuits can not only perform the all-pass function, but also exercise an independent control over the phaseshift and/or gain by voltage and/or digital signals
