transistor-resistor network [Y] matrix

Need help with the following (your assitance is much appreciated)


1)The admittance matrix of a resistor in parallel with the output (collector) of a transistor

2) The admittance matrix of a resistor in parallel with the input (base)of a transistor


Note this is a normal bipolar NPN
