• The branch of electronics consisting of circuits which process analogue quantities is called analogue electronics. For instance, the public address system is an analogue system in which the microphone converts sound into a continuously varying electric potential.

•  This potential is an analogue signal which is fed into an amplifier. Amplifier is an analogue circuit which amplifies the signal without changing its shape to such an extent that it can operate a loudspeaker. In this way, loud sound is produced by the speaker. Radios, televisions and telephones are a few common devices that process analogue signals.

• The quantities whose values vary in non-continuous manner are called digital quantities. Digital version of analogue signal. Digital quantities are expressed in the form of digits or numbers. The branch of electronics which deals with digital quantities is called digital electronics. Digital electronics uses only two digits ‘0’ (zero) and ‘1’ (one) and the whole data is provided in binary form due to which processing of data becomes easy.

• In our daily life, the quantities that we perceive by our senses are usually analogue quantities which cannot be processed by digital circuits. To overcome this problem, a special circuit has been designed which converts in binary form the analogue signal into a digital one in the form of digits in binary form. This circuit is known as analogue to digital converter (ADC).

• This binary output is then processed by a computer which also gives output in digital form. The output of the computer is again converted into an analogue form by a circuit known as digital to analogue converter (DAC). As the output of DAC is an analogue signal, it can be readily sensed by us. Thus, electronic systems used at present consist of both analogue and digital type circuits.
• Important 10th class physics chapter 16 numericals solved for all students of Punjab  Textbook Board.
• BASIC OPERATIONS OF DIGITAL ELECTRONICS – LOGIC GATES: A switch has only two possible states. It could be either open or closed. Similarly, a given statement would be either true or false. Such things which can have only two possible states are known as binary variables. The states of usually represented by the digits ‘0’ and ‘1’.
• Important 10th class physics chapter 16 numerical for all students of Punjab  Textbook Board.
•  Suppose we form a circuit by connecting a lamp to a battery using a switch S. We call state of switch as input and state of current or lamp as output. When the switch is open no current passes through the circuit and lamp is OFF. 
• "These states are also called logic states or logic variables".
