Microprocessor programmable universal active filters (Maxim Integrated Products lnc.)
Maxim's MAX260/261/262 series of ICs contain two double filter sections of which the response can be set for each section individually by means of a microprocessor output port or a microcomputer system. This brings the programming of roll-off frequencies and Q factors at the flick of a switch within easy reach. Handy, too, in the laboratory, such a computer-controlled filter bank!
