Unformatted text preview: 3) The simulated bandwidth of the circuit is measured when the output of the simulation reaches 0.7071, which is 1 divided by the square root of 2. This corresponds to a 3dB drop in the simulation which is very close to our measured value of the bandwidth of 3.4. The simulation’s value at 0.7071 was about 3.39. The reason the circuit reaches its bandwidth at high frequencies is because this circuit was a low-pass filter, meaning that most of the lower frequencies of the sound wave are passed while the higher frequencies are not all passed....
