hii

i make an adc by simulink

but its discrete transfer function block only has z^-1 or z^-2 (integer)

if i need z^-(1/2) or z^-(3/2) to make a transfer function block like this

anyone know how to do ?

thanks

Re: simulink

Couldn't you just multiply both the numerator and denominator by \[z^2\].
