  • Second-order canonical active filter
    Patent number: 3993959
    Abstract: A high-pass notch filter with variable gain that may be greater than unity is realized using a differential amplifier and only two capacitors that can be equal. The transmission zero and pole frequency are completely independent of the amplifier d-c gain. Three embodiments of the filter are illustrated, thus extending the available range of the gain to cover all requirements.

  • Functionally tunable active filter
    Patent number: 3946328
    Abstract: A family of RC active filters in which band-pass, low-pass notch, high-pass notch, band-stop and all-pass second order sections may be realized. The filters provide unidirectional functional tuning of the four basic parameters .omega..sub.o, Q.sub.o, .omega..sub.z and Q.sub.z through resistive trimming.
