Development of Sensitive Lock in Amplifier for Electron Spin Resonance Spectrometer
Dept. of Physical Science, Kakatiya Institute of Technology & Science, Warangal (A. P)
A Linear Monolithic four quadrant Analog Multiplier has been used for the detection of electron spin resonance signals; in connection with a phase lock loop. The detection system employs an audio frequency modulation of the magnetic field followed by a phase sensitive detector where in analog Multiplier is used.
