Hi, Mark !

> I assume that t represents the sample interval 

No, t is just the time. 

You need just to do the following:

0<=k<=N-1

hi[k]=h[k]*cos(w0*(k-N/2+1/2)*T)
hq[k]=h[k]*sin(w0*(k-N/2+1/2)*T)

N - FIR length
T - sample period
h - LPF FIR taps
w0 - the center of the resulting BPFs

All the best !
