Discrete-time model: y(t) = [B(q)/F(q)]u(t)

B(q) = -0.5527*q^-1 + q^-2 - 0.81*q^-3 - 0.2231*q^-4 + 0.459*q^-5

F(q) = 1 - 7.47*q^-1 + 4.78*q^-2 - 1.8502*q^-3

q^-1 is a time-shift operator that compactly represents such difference equations using q^-1u(t)=u(t-T).where y(t) is the output, u(t) is the input, and T is the sampling interval. This q description is completely equivalent to the Z-transform form: q corresponds to z.

assume u(1)=1

Dear all, how can i get the value of y(1)? Can demonstrate the calculation?

Urgent help needed

Thank you very much
