Abstract :
A new family of active variable equalisers is introduced. The proposed variable equaliser transfer function is generated from Bode´s classical transfer function using a new mathematical transformation. The new circuit uses a single operational amplifier and the required full range of variation is obtained by varying a single resistor Rv from zero to Ro (a reference resistance). The variable equaliser circuit requires a single shaping grounded impedance for realisation.
