Working
Audio amplifierSound signal is received by AUDIO AMPLIFIER .
Here the given sound signal is converted into
electrical signal and then amplified by usingtransistors.

Flip flop circuit
It consists of two transistors, one for the onposition and the other for the off position.
For this reason it is also known as bi-stable multivibrator.

Circuit amplifier
The outcome of this circuit is Electrical signal.
This electrical signal is very weak so we have use
another transistor in this circuit.

ADVANTAGES
1. The primary application involves an elderly ormobility-impaired person.
2. We can turn something (e.g. a lamp) on and off fromany location in the room (e.g.
while lying in the bed) simply by clapping our hands.
3. Low cost and reliable circuit.
4. Complete elimination of man power.5. Energy efficient.

DISADVATAGES
1. It is generally cumbersome to have to clap ones handsto turn something on or off
and it is greatly seen as simpler for most use cases touse a traditional light switch.
2. Unless we use a filter in the circuit , it is not thatadvantageous. So that circuit
activates only for clap of particular frequencies andthen it becomes accurate.
