Experiment 10:Signal Processing Application

This was a Group Experiment performed by Aishwarya Bannore, Varad Choudhari, Gauri Joijode, Amisha Khimani and Apoorva Laharia. We choose "Morse Code Generator 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)

Patent Review :
Portable Morse Code Signaling DevicePatent No. : US3668684
Inventors : Johnson, Donald W.
                 Stovall, Ronald J.
                 Wheelock, Larry A.
Publication : 20th December, 1970
Summary :
This invention tells about a signaling device which flashes a coded signal which is electronically generated. A diode encoder having a plurality of switches is provided to select flip-flops that are set which, upon clearing of the shift register, provide a Morse code signal. Two oscillators are used, one to pulse the shift register and a second one to pulse diode encoder for resetting flip-flops.
Applications :
Morse code is used to a encode a message to be transmitted by sound or light signal. Signals are encoded for privacy purposes. The above device will send the Morse code in the form of a light which can be a mean of communication.

Summary :
This research paper proposes a technique of generation of Morse code using a alphanumeric keypad and microcontroller interface. Morse code being a reliable source of transmission for private data, is used in military and navy applications. For a person with no idea of Morse code wants to generate it for sending messages this method can be used.
Hardware :
The alphanumeric keyboard is interfaced to the microcontroller which is used to type the message in English. The microcontroller changes this message to Morse code which is the displayed on the LCD.
Application :
Morse code is very crucial in communication for sending distress calls and in Military and Navy communication systems.
