Question

Is it necessary to use an above- and below-ground power supply when a 741 operational amplifier is to be used as an oscillator? ________ Is the hysteresis loop connected to the inverting or noninverting input? _____ The hysteresis loop is actually a______ An op amp has a capacitor with a value of 0.1 mu_f and a resistor with a value of 4.7 ohm connected to the inverting input. What would be the output frequency of the oscillator?____ What is the difference between an oscillator and a pulse generator? ______

Explanation / Answer

(1)

above and below ground power supplies are not a mandatory, we can use positive and negative supply voltages. to get the waveform with in the saturation ragnges
