Impedance relation between 2 Bjts

[samy555]

If there are two BJT small signal amplifiers (common Emitter) cascade connected using a suitable decoupling cap
The first preamp has an o/p imeadance Zo, and the second has an i/p impedance Zin
Now we have Zo and Zin and a cap between them
My question is: Is the connection series or parallel? That, is the o/p voltage divided or the o/p current?

Neither or both - it's basically just a simple resistive attenuator (top leg the output impedance of the first stage, and bottom leg the input impedance of the following stage).
