This was a Group Experiment performed by Ninad Chitnis,Saish Desai,Vaibhavi Dichwalkar,Shrinish Donde, Akash Bangera, Ankesh Patil. We choose "Morse Code Generation from a given Analog Signal" as an application.
Problem Definition :
1) Accept Analogy input and convert it into Digital Signal(Binary).
2) Covert Binary to Morse and implement the dots and dashes as 0 and 1 respectively.
(Dots = 1 = LED ON, Dash = 0 = LED OFF)

Summary :-
Morse code is a code in which letters are represented by combinations of long and short light or sound signals.It transmits text as a series of on-off tones,lights or clicks. The code which is to be transmitted is loaded into preset-able counters.Switch mean is used to connect the binary level to a specific memory location.The counter thereby sends data sequentially generating Morse Code.It sends one digit at a time.The next lesser significant digit to the address and binary counter are recycled. Switching means are used for the generation of leading zeros and for selectively abbreviating the international Morse code of certain digit comprising the numbers.

Applications:-
It allows physically handicapped person to communicate by the means of tap or blink.
In aviation, pilots use the Morse code to ensure whether the stations are servicable or not by transmitting a short set of identification numbers.

Summary:-
Morse code helps physically impaired persons to communicate easily. However they have difficulties in maintaining a stable type. Hence the threshold and prediction method is in demand. In threshold prediction, the Morse code time series with unit time period and ratio are used.Two least mean square predictors are applied to trace the dash and the dot interval and the dot-dash difference and a predicted threshold based on a variable ratio decision rule is used to distinguish between dashes and dots. The same method is applied to identify the character space.

Well explained.
ReplyDeleteGood application!
ReplyDeleteAnother application is the use of Morse code in scene defense systems
ReplyDeleteYes,it is already used in Army to send encrypted messages.
DeleteMorse code is basically used for communication in army or satellite communication as it is highly efficient.
ReplyDeletealso secret messages can be transmitted easily
DeleteIntresting application!
ReplyDeleteGood application.
ReplyDeleteThe Processing of real time signal was well understood from this application.
ReplyDeleteMorse code is interesting
