Abstract |
Filters have always been indispensable when it comes to Signal Processing, may it be analog signal processing or the digital signal processing. Analog signal processing has always been the superset of the digital signal processing. Later came the advent of digital systems. Even some of the pioneer digital filters relied on the techniques used for their analog parents. Still today, some digital filters depend on the simulation of analog filters in order to achieve from some of their interesting properties. Filters varying their resonant frequency in response to an input control voltage which is generated via analog multipliers or the phase detectors in a negative-feedback circuit are called-self tuning filters. They allow the automatic tuning of bandwidth, quality factor and center frequency. Keywords- Resonant Frequency; Analog Multiplier; Phase Detectors; Voltage Controlled Filters; Bandwidth; Quality Factor. | |||||||||
