Title: Peak Follower and Memory
IPC: G01R19/04
Filed: 1967-11-17
Abstract: 1,192,939. Peak voltage detection. FOXBORO CO. Nov. 17, 1967. [Dec. 15, 1966], No. 52490/67. Heading G1U. An apparatus for providing a steady output signal corresponding to a selected instantaneous input signal e.g. the peak value of a pulse from a chromatograph analyzer applied to input terminals 11, 12, incorporates a relay switch 18 which when actuated applies the input signal to a level retaining circuit incorporating a high input impedance amplifier 20 and a capacitor 27 connected across the amplifier input circuit to store the applied input. A rate detecting circuit 29 inter-connected with the input terminals determines the rate of change of the input and provides an energizing signals while this is positive to actuate the energizing coil 48 of the relay switch so that the capacitor charges in accordance with the input. When the switch is deenergized, the amplifier provides an output corresponding to the (steady) charge on the capacitor at terminal 22. Negative feedback is applied through resistor 25. In the rate detecting circuit, the input is applied to the base emitter junction of the transistor 29 via differentiating capacitor 30. So long as the transistor is kept on by this signal, the relay winding 48 remains energized by the supply 38 to keep the switch 18 closed, so that the capacitor 27 charges in accordance with the input. When the rate of change of input reduces to zero at the signal peak, however, the transistor path opens, the relay de-energizes and the switch 18 opens.
