(b) Identify the equivalent gate for the following circuit and write its truth table.
(a) Principle on which a transistor-amplifier works as an oscillator-
The transistor-amplifier oscillatory circuit consists of an inductive
coil of inductance L connected in parallel with a capacitor of capacitance C.
The frequency of oscillation in the circuit depends upon the values of L and C.
The actual frequency of oscillation is the resonant.
The transistor-amplifier oscillatory circuit receives dc power from the
battery and converts it into ac power for supply to the circuit. The
oscillations occurring in the circuit are applied to the input of the
electronic amplifier and due to amplifying properties of the amplifier, we get
increased output of these oscillations which can be supplied to the circuit to
meet the losses.
( b) The equivalent gate for the following circuit is AND gate and below is its Truth Table
