Symbol logic

      Boolean algebra derives its name from the mathematician George Boole. Symbolic Logic uses values, variables and operations :

• True is represented by the value 1.
• False is represented by the value 0.

      Floating Point Numbers

      A real number or floating point number is a number which has both an integer and a fractional part. Examples for real real decimal numbers are 123.45, 0.1234, -0.12345, etc. Examples for real binary numbers are 1100.1100, 0.1001, -1.001, etc. In general, floating point numbers are expressed in exponential notation.

     Error Detecting and Correction Codes

     For reliable transmission and storage of digital data, error detection and correction is required. Below are a few examples of codes which permit error detection and error correction after detection.

      Binary Codes

      Binary codes are codes which are represented in binary system with modification from the original ones. Below we will be seeing the following:

     Code Conversion

     Converting from one code form to another code form is called code conversion, like converting from binary to decimal or converting from hexadecimal to decimal.

   Logic Circuits 

Boolean algebra is ideal for expressing the behavior of logic circuits.

A circuit can be expressed as a logic design and implemented as a collection of individual connected logic gates.

     Digital electronics is classified into combinational logic and sequential logic. Combinational logic output depends on the inputs levels, whereas sequential logic output depends on stored levels and also the input levels. 

     What is the output of AND gate in the circuit below, when A and B are as in waveform?

     Tp is the gate delay of respective gate.
