(a) Draw the circuit diagram for studying the characteristics of a transistor in common
emitter configuration. Explain briefly and show how input and output characteristics
are drawn.
(b) The figure shows input weve forms A and B to a logic gate . Draw the output waveform
for an OR gate . Write the truth table for this logic gate and draw the output waveform
for an OR gate . Write truth table for this logic gate and draw its logic symbol.
