UJT Relaxation Oscillator

UJT Relaxation Oscillator  Objects:- Study of zener diode as voltage regulator. Study of static emitter characteristics of UJT- uni-junction transistor on oscilloscope. Study of effect of V on peak point and valley point voltage and valley point current. Operation of UJT relaxation oscillator and its use as SCR trigger circuit. Control of UJT trigger pulses with shunt transistor. Study of variations in gate resistance & capacitance, resistance of source & drain and their effect on trigger pulse characteristics of UJT relaxation oscillator. Various configurations of UJT relaxation oscillator type 1(low output impedance), type 2 (moderate output impedance) and type 3 (high output impedance).
