Analysis of Double Hashing and Separate Chaining

Analysed asymptotic complexities and collision rate of queries in Double Hashing and Separate Chaining techniques.

View Project

Symbolic Differentiation

Constructed a Binary Tree by parsing valid fully parenthesised infix expression and computed its derivative by traversal. The parser was made to support a variety of functions like algebraic, trigonometric, exponential & composite functions.

Sound Detector Switch

A potential developed across Condensor Mic 's terminals due to sound is used as input to CE transistor whose output goes to a 555 timer IC in mono-stable configuration which delays the trigger signal and the output pulse from the timer goes to D-type flip flop which changes the state of the output from ON-OFF or OFF-ON.
