| Abstract: | 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 |
