| Abstract: | This paper introduces the design and implementation of 1 D variable cutoff frequency (VCF) digital filters. A lowpass to highpass transformation and a lowpass to bandpass transformation for VCF infinite impulse response (IIR) filter are presented. The transformed highpass and bandpass filters are implemented in a network structure in which the cutoff frequencies are variable by adjusting single parameter. |
