Task 3. In the circuit of the figure, the switch is closed at the moment t = 0. The initial voltage of the capacitor is zero, and the initial current of the coil is also zero. a) Write the voltage equation of the circuit in Laplace form. b) Using the voltage equation, solve the current /(s) and write down the solution of the task in its entirety in your answer. DC voltage E is 160 V. R= 4.8 ohms, L = 4 H, and C = 0.25 F. E k R L C
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 modified with the help of the other one. The process of computing it and the result function is known as convolution. After one is reversed and shifted, it is defined as the integral of the product of two functions. After producing the convolution function, the integral is evaluated for all the values of shift. The convolution integral has some similar features with the cross-correlation. The continuous or discrete variables for real-valued functions differ from cross-correlation (f * g) only by either of the two f(x) or g(x) is reflected about the y-axis or not. Therefore, it is a cross-correlation of f(x) and g(-x) or f(-x) and g(x), the cross-correlation operator is the adjoint of the operator of the convolution for complex-valued piecewise functions.
