To find the step response we have to transfer from time domain to Laplace domain..again by transforming from Laplace domain to time domain we will get step response..step response means the output response when input is step signal..the impulse response means the output response when input is impulse signal
Exercise 2.5 response of the LTI system with impulse response h(t)-e cos(2t)u(t)
Show that the system with impulse response h(t) = e-2t cos(10nt) u(t) • Is it stable? Is it causal?
Consider an LTI system with the impulse response h(t) = e- . Is the system casual? Explain. Find and plot the output s(t) given that the system input is x(t) = u(t). Note that s(t) in this case is commonly known as the step response of the system. If the input is x(t) = u(t)-u(t-T). Express the output y(t) as a function of s(t). Also, explicitly write the output y(t) as a function of t. a) b) c)
Consider a continuous-time LTI system S with impulse response h(t) = 2(u(t + 1)-u(t 1)). Determine the values of the amplitude scaling and the tme shifting that takes place when each of the following input signals is provided to the system S. Don't use the convolution integral, instead use the result about how LTI systems respond to complex exponential signals.
