What are the advantages of Laplace transform?
The advantage of using the Laplace transform is that it converts an ODE into an algebraic equation of the same order that is simpler to solve, even though it is a function of a complex variable. The chapter discusses ways of solving ODEs using the phasor notation for sinusoidal signals.
What are the advantages and limitations of Laplace transform?
It is only used to solve complex differential equations like great methods. This method is only used to solve the differential equations using known constants. If the equation has unknown constants we cannot solve them using the Laplace Transform method.
What is the difference between Z-transform and Laplace transform?
The Z-transform is used to analyse the discrete-time LTI (also called LSI - Linear Shift Invariant) systems. The Laplace transform is used to analyse the continuous-time LTI systems. The ZT converts the time-domain difference equations into the algebraic equations in z-domain.
What are the disadvantages of Z-transform?
Limitations – The primary limitation of the Z-transform is that using Z-transform, the frequency domain response cannot be obtained and cannot be plotted.
