(iv) investigate how the voltage gain changes with frequency between 1kHz and 1MHz. v) build a prototype of the circuit and measure the voltage gain for the same frequency range. (vi) compare the results from theory (Assume B =100; show your calculation in details), simulation and measurements (c) Operational amplifier circuits (1) identify the pin-out of an operational amplifier and relate it to the schematic diagram. Simulate the following inverting amplifier (Measure Vo and Bandwidth Fy, Explain your producer and insert screenshot of your work) then calculate the gain-bandwidth product (GB), Repeat your simulation with R2 = 20K.
