# Discrete transfer functions with different sample rates

is there a way to deal with a connection of two discrete transfer functions with different sample rates?

E.g.: $$G = G_1G_2$$ with sampling rate of $$G_1$$ being $$T_1=1$$ and for $$G_2$$ being $$T_2 = 2$$.

How can I describe/analyse $$G$$?

• You can model $G=G_1{G'}_2$, where ${G'}_2$ is the output of $G_2$ after a zero order hold. – N74 Oct 9 at 20:33
