Class 12 ISC- Java
Class 12th Java aims to empower students by enabling them to build their own applications introducing some effective tools to enable them to enhance their knowledge, broaden horizons, foster creativity, improve the quality of work and increase efficiency.
It also develops logical and analytical thinking so that they can easily solve interactive programs. Students learn fundamental concepts of computing using object oriented approach in one computer language with a clear idea of ethical issues involved in the field of computing
Class 12th java topics includes revision of class 11th, constructors, user-defined methods, objects and classes, library classes , etc.
Encoders & Decoders
Encoder
- Process of converting one type of signal into other type is called as encoding.
- The circuit which performs such task is known as encoder
Decimal to Binary Encoder : It converts decimal number into its binary equivalent.
No. of inputs : 10 (0 to 9)
No. of outputs : 2n ≥ I → 24 ≥ 10 → n = 4
There will be 4 outputs.
Hexadecimal to Binary Encoder : It converts hexadecimal number into its binary equivalent.
No. of inputs : 16 (0 to 9 then A to F i.e. 10 to 15)
No. of outputs : 2n ≥ I → 24 ≥ 16 → n = 4
There will be 4 outputs.
No. of inputs : 10 (0 to 9)
No. of outputs : 2n ≥ I → 24 ≥ 10 → n = 4
There will be 4 outputs.
No. of inputs : 16 (0 to 9 then A to F i.e. 10 to 15)
No. of outputs : 2n ≥ I → 24 ≥ 16 → n = 4
There will be 4 outputs.
Decoder
It is a circuit which change n bit
binary input lines to 2n output lines.
