Q3) The figure below shows the small signal equivalent circuit of a single stage transistor amplifier. The transistor has the following small signal parameters: $h_{ie} = 3k\Omega$, $h_{fe} = 90$
a) The input signal to the amplifier, $V_i$, is a sinewave of 10mV amplitude at a frequency of 1kHz. Assuming that the reactance of $C_1$ is small at 1kHz, calculate
i) The amplitude of the output signal $V_o$.
ii) The amplitude of the output signal $V_o$ when the output of the amplifier is connected to a further circuit that has an input impedance of $10k\Omega$.
(b) Calculate a value for $C_1$ if the above amplifier is to have a low frequency cut-off of 40Hz.
