How to Obtain an Impulse Response Once a transform (or transfer function) G(s) has been deﬁned in MATLAB, operations can be performed to compute and display the corresponding time function g(t), known as the inverse Laplace transform. If the poles are known, G(s) can be written as a partial-fraction expansion …

Consider the relationship between voltage and current for a resistor (Ohm’s Law). Suppose that c current I1 (the excitation or input) is applied to a resistor, R. then the resulting voltage V1 (the response or output) is \[{{V}_{1}}={{I}_{1}}R\] Similarly, if I2 is applied to R, then V2=I2R results. But if …
