"Witrynaimpulse (sys) plots the response of a dynamic system model to an impulse input. The model sys can be continuous or discrete. For continuous-time sys, the impulse input is the Dirac impulse δ (t). For continuous-time sys with direct feedthrough, impulse ignores the infinite pulse at t = 0. " - Impulse response method

Witryna14 lut 2024 · Given the system equation, you can nd the impulse response just by feeding x[n] = [n] into the system. If the system is linear and time-invariant (terms we’ll de ne later), then you can use the impulse response to nd the output for any input, using a method called convolution that we’ll learn in two weeks. For today, let’s get some ... WitrynaSample the analog impulse response using Equation (8.38) and apply the z-transform to the digital impulse function to obtain the digital filter transfer function. 4. Verify the frequency response, and output the difference equation. If the frequency specifications are not net, quit the design method and use the BLT.
