Determine and plot the response of an accumulator for an input sequence 𝑥[𝑛] = 𝑢[𝑛] + 2𝑢[𝑛 − 1] − 3𝑢[𝑛 − 3]. Consider the system is at rest. use the function filter

Consider the difference equation of an accumulator

𝑦[𝑛] = 𝑦[𝑛 − 1] + 𝑥[𝑛]

The transfer function of this equation is given by taking z-transform as

𝑌[𝑧] = 𝑧−1𝑌[𝑧] + 𝑋[𝑧]

𝑇[𝑧] = 𝑌[𝑧]/X[𝑧] = 1/1 − 𝑧−1

Hi

You can refer this example to plot the response using filter function.
