Convolution is a formal mathematical operation, just as multiplication, addition, and
integration. Addition takes two numbers and produces a third number, while convolution takes
two signals and produces a third signal. Convolution is used in the mathematics of many fields,
such as probability and statistics. In linear systems, convolution is used to describe the
relationship between three signals of interest: the input signal, the impulse response, and the
In this equation, x1(k), x2(n-k) and y(n) represent the input to and output from the system
at time n. Here we could see that one of the input is shifted in time by a value every time it is
multiplied with the other input signal. Linear Convolution is quite often used as a method of
implementing filters of various types.
Since the advent of electronic watches that incorporate small computers, digital displays have also been available. A digital display simply shows the time as a number, e.g., 12:40 AM instead of a short hand pointing towards the number 12 and a long hand pointing towards the number 8 on a dial.The first digital watch, a Pulsar prototype in 1970, was developed jointly by Hamilton Watch Company and Electro-Data. John Bergey, the head of Hamilton's Pulsar division, said that he was inspired to make a digital timepiece by the then-futuristic digital clock that Hamilton themselves made for the 1968 science fiction film 2001: A Space Odyssey. On April 4, 1972 the Pulsar was finally ready, made in 18-carat gold and sold for $2,100 at retail. It had a red light-emitting diode (LED) display. Another early digital watch innovator, Roger Riehl's Synchronar Mark 1, provided an LED display and used solar cells to power the internal nicad batteries.Despite these many advances, almost all watches with digital displays are used as timekeeping watches. Expensive watches for collectors rarely have digital displays since there is little demand for them. Less craftsmanship is required to make a digital watch face and most collectors find that analog dials (especially with complications) vary in quality more than digital dials due to the details and finishing of the parts that make up the dial (thus making the differences between a cheap and expensive watch more evident).
The title of the project is DIGITAL CALENDAR which is an embedded based project. An embedded project is a combination of hardware and software. Microprocessors and micro-controllers are widely used in such embedded system products. Each embedded system is unique and highly customized to the application at hand. The main basics that includes in embedded programming are either assembly programming or it may be high level languages such as C,C++ or Embedded C. This project ³DIGITAL CALENDAR´ using micro controller is an advanced digital calendar, which displays the Seconds, Minutes, Hours, Date, Day, month over the LCD display. It has the advantage of setting these features. It has an 8-bit micro-controller which runs on the program embedded in ROM.
