... .. 0 O .. . . .O .. . e A student intends to connect a TL082 OP-AMP as a voltage follower, to "follow" the voltage generated by a potentiometer but makes some mistakes in the breadboard wiring: *He took Pin 3 and connected it to Pin 1, but this is wrong as Pin 3 is supposed to go to Pin 6, fix this. *A meter lead is supposed to go to Pin 6, the output not to Pin 1. A 3rd mistake results in no output but this he cannot discover, help him. Sketch a schematic diagram of this circuit, fixing the above (don't forget to include the Voltmeter) and determine what the voltmeter's indication will be, explaining why it is such. 12 V TL082 12 V AA OFF COM
A voltage-controlled oscillator (VCO) is an oscillator that oscillates at a constant frequency and is controlled by an external bias voltage. A VCO's output is a frequency, and its input is a bias or control signal, which can be either dc or ac voltage. Which of the following assertions is a TRUE statement? Select your answer. The output frequency changes or deviates accordingly when ac voltage is applied to the VCO input. The output frequency changes or deviates appropriately when a square voltage is delivered to the VCO input. The output frequency changes or deviates appropriately when a DC voltage is delivered to the VcO input. The output frequency fluctuates or deviates accordingly when a dc or slowly shifting ac voltage is introduced to the VCO input.
