Laboratory Goals

The objectives of this laboratory session are as follows:

Introduction


LTspice Low Pass Filter

The following LTspice schematic of a low pass filter was designed and simulated with a voltage source (sine,AC), R = 100k and C1 = 50 n, with three different simulation commands (.Op, .tran, .AC) :

LTspice Low Pass Filter

The following figure shows the designed and simulated low pass filter circuit:


figure 1

Low Pass Filter Operating Point

The following figure shows the operating point of the simulated low pass filter.


figure 2

Low Pass Filter Simulation

The following figure shows the transient output of the simulated low pass filter.


figure 3

Low Pass Filter Simulation

The following figure shows the simulated output of the low pass filter.


figure 4
From the simulation result, it is clear that the low pass filter characterstics matches the simulation output.
