simulations for all simulations, provide screenshots showing the schematics and the plots with the simulated values properly labeled. draw the schematics for the circuits in fig. 3 with the calculated component values. perform the following simulations for each circuit: 1. obtain the magnitude and phase bode plots of the transfer function using ac simulation, and measure the 3-db frequencies and passband gains. also measure the magnitude and phase of the transfer function at 4khz and 6khz. 2. apply the input vi(t)
