Which of the following options is true for a linear time-invariant discrete time system that obeys the difference equation?y[n] – ay[n - 1] = b0x[n] – b1x[n - 1]

When x[n] = 0, n 0 is solely determined by the function x[n]

y[n] is unaffected by the values of x [n - k]; k > 2

The system is necessarily causal

The system impulse response is non-zero at infinitely many instants
