摘要：
A circuit is presented of an active selective filter, the resonance frequency of which can be varied through coded TTL address inputs. The relationship between address and resonance frequency can be formulated mathematically, and makes the filter suitable for control applications by use of a microprocessor system. The bandwidth and amplification are independent of the prevailing resonant frequency.
