A continuous-time filter with transfer function H(s)=(2s+6)/(s2+6s+8) is converted to a discrete-time filter with transfer function G(z)=(2z2-0.5032z)/(z2-0.5032z+k) so that the impulse response of the continuous-time filter, sampled at 2 Hz, is identical at the sampling instants to the impulse response of the discrete time filter. The value of k is
