Explanation Given data: The Laplace transform function, F ( s ) = 5 + 6 s + 4 − 7 s s 2 + 25 Formula used: Write the general expression for the inverse Laplace transform. f ( t ) = ℒ − 1 [ F ( s ) ] (1) Refer to Table 15.2 in the textbook. Write the general expressions to find the inverse Laplace transform function. ℒ − 1 [ 1 s + a ] = e − a t u ( t ) (2) ℒ − 1 [ 1 ] = δ ( t ) (3) ℒ − 1 [ s s 2 + ω 2 ] = cos ω t u ( t ) (4) Here, s + a is the frequency shift or frequency translation. Write the general expression to calculate for the unit step function. u ( t ) = { 0 , t < 0 1 , t > 0 (5) Calculation: Consider the function, F ( s ) = 5 + 6 s + 4 − 7 s s 2 + 25 Substitute 5 + 6 s + 4 − 7 s s 2 + 25 for F ( s ) in equation (1)

Transfer function

A transfer function (also known as system function or network function) of a system, subsystem, or component is a mathematical function that modifies the output of a system in each possible input. They are widely used in electronics and control systems.

Convolution Integral

Among all the electrical engineering students, this topic of convolution integral is very confusing. It is a mathematical operation of two functions f and g that produce another third type of function (f * g) , and this expresses how the shape of one is …
