Upload answer sheets 10 Determine the voltage gain of the following op-amp circuit with the potentiometer kept fully up,
(1) Determine the voltage gain of the following op-amp circuit with the potentiometer kept fully up, precisely mid position, and fully down (6 Marks) M W (1) A sine wave of 0.5V peak voltage is applied to an inverting amplifier using R1+100 and Rf=50k. It uses the supply voltages of #12V. Determine the output and sketch the waveform. If now the amplitude of input sine wave is increased to 5V peak, what will be the output? Is it practically possible? Sketch the waveform (4 Marks)
Determine the input impedance and Vout of the circuit shown below. Assume the input voltage of -30dB A DAN AL 4. WWW.
(a) The 741 IC is used as an inverting amplifier with a gain of 100. The input signal has a variable frequency and maximum amplitude of 20mV peak. What is the maximum frequency of the input at which the output will be undistorted? Assume that the amplifier is initially nulled. (5 marks) (b) Design an op-amp as a two-stage amplifier with gains of +10, and -18. Use a 2700 feedback resistor for both the circuits. What output voltage will result for an input of 150 mV?
