Abstract

1347043 Calibration of amplifiers MEDICOR MUVEK 12 May 1971 [12 May 1970] 14558/71 Heading G1U A push-pull amplifier 1, 2, receiving a signal balanced with respect to earth 9 over input resistors 4, 5, is calibrated by connecting a reference potential across the input resistor 4, this potential being obtained from an oscillator 19, 20 coupled to a coil 18 whose output is rectified 17, smoothed 16, and stabilized by a Zener diode 13. The oscillator 19, 20 is normally inoperative, and to effect calibration D.C. supplies are applied to it by closure of a contact 21.
