5.3-16 n A professor recently received an unexpected $10 (a futile bribe attached to a test). Being the savvy investor that she is, the professor decides to invest the $10 into a savings account that earns 0.5% interest compounded monthly (6.17% APY). Furthermore, she decides to supplement this initial investment with an additional $5 deposit made every month, beginning the month immediately following her initial investment (a) Model the professor's savings account as a constant coefficient linear difference equation. Designate y[nas the account balance at month n, where corresponds to the first month that interest is awarded (and that her $5 deposits begin). (b) Determine a closed-form solution for y[n]. That is, you should express y[n] as a function only of n. (c) If we consider the professor's bank account as a system, what is the system impulse response h[n]? What is the system transfer function H[z]? (d) Explain this fact: if the input to the professor's bank account is the everlasting exponential x[n] = 1" = 1, then the output is not y[n] = 1"H[1] =H[1]. = 0 5.3-16 n A professor recently received an unexpected $10 (a futile bribe attached to a test).
