Convolution with a rectangular pulse

Knowledge in eletrodynamic theory and fundamental eletronicsThe output signal of an LTI (linear time-invariant) system with the impulse response h(t)is given by the convolution of the input signal x(t)with the impulse response of the system.The upper figure shows (red) and (blue). The gray area in the figure is the area under the product of the two functions. It equals the value of the convolution integral and the value of the output signal at time. This value is marked as a blue point in the lower figureComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Físic
