Show how you will obtain an AND gate using only NOR gates. Draw the truth table for this arrangement of gates.
(ii)[2.5]
For a common emitter transistor amplifier, the audio signal voltage across the collector resistance ($r_c$) of $2\text{ k}\Omega$ is $2\text{ V}$. If the current amplification factor ($\beta$) of the transistor is $100$, calculate the input signal voltage ($V_{BE}$) and base current ($I_B$) for base resistance of $1\text{ k}\Omega$.
