Discrete Vs Analog I/O Signals Vs Digital Signal

         The first step of digitization is to sample the analog signal. Output of this process is a discrete time signal. At this point, there is no constraint on amplitude of the output signal. Figure below shows both the signals.   ...

What are Static Variables and functions in C ?

In C, functions are global by default. The “static” keyword before a function name makes it static.Unlike global functions in C, access to static functions is restricted to the file where they are declared. Therefore, when we want to restrict access to functions, we make...

Difference between float and double in C/C+

Double has 2x more precision then float.float is a 32 bit IEEE 754 single precision Floating Point Number1 bit for the sign, (8 bits for the exponent, and 23* for the value), i.e. float has 7 decimal digits of precision.Double is a 64 bit IEEE 754 double precision Floating...
