Introduction - Logic is the study and analysis of valid arguments. The arguments are in the form of statements or propositions, which are either true or false, but not both. There are also some statements, which appear to be true and false at the same time. They are called paradoxes. The study of l..

We explain C5 with the following example. Consider the statement "either the monsoon break in June or the rivers are dried" Let p: The monsoon does not break in june q: rivers are dried Clearly 'if p then q' is true if p is true and q is true. That is, the conditional statement of the above stat..

'>Framing of Formulae A formula is formed by using: (a) mathematical symbols and variables (b) given conditions, and (c) simplification. Indices If m is a positive integer, a x a x a .... m times is written as am. a is called the base and m is the power. We read it as "a raised to the pow..

There are digital circuits which either allow a signal to pass through or stop it. The circuits other wise called as gate allows the signal to pass only when some logical condition are satisfied. Under such condition the circuits are called logic gates. They are building blocks of any digital syste..
