First-Order Transfer Functions

A transfer function is the ratio of the output to the input of the system. The system response is determined from the transfer function and the system input. A Laplace transform converts the input from the time domain to the spatial domain. The transformed spatial input is multiplied by the transfer function to get the output in the spatial domain. It is then converted back to the time domain using an inverse Laplace transform. This simulation shows the responses to a first-order transfer function. You can vary the magnitude of the input and the time constant, τ. The time constant is related to how long a system takes to reach the new steady state. The input can be a step function, a ramp, or a sinusoidal input
