Signal Processing Application

MORSE CODE

Amidst all the submissions and practicals round the corner, we were asked to write a review on an IEEE paper and a patent issued on the same application. After a lot of discussion over the topic with group mates, we agreed upon a common topic : MORSE Code Generation

Patent Review

Patent referred is : International Morse Code Number Generator

Patent Number : US4292624
Inventor : William K. Serp
Date of Publish : Sept 29, 1981
Application Number : 517,813

What is a Morse code? according to wikipedia, 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. 
This patent has clearly stated that 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 include Aviation and making communication easier for handicapped people. 
IEEE Paper Review

Paper referred is : Automatic Morse Code recognition with adaptive variable ratio threshold prediciton for physically handicapped persons

Morse Code can bridge the gap of communication for people with physical limitations. This paper has suggested an Adaptive variable radio threshold prediction algorithm (ADVTP) to strengthen the idea of automated recognition of unstable morse code. The paper has proved that Adaptive signal processing is faster and cheaper when compared to artificial neural networks.

  3. Most of the physically disabled people have difficulties in maintaing a stable typic of morse code. This is 'unstable'.

Chebyshev Filter Design

Chebyshev Filter Design Having designed a filter by Butterworth design method previously, designing filter by Chebyshev Method requires calculation of a lot more parameters than butterworth method. We designed Chebyshev 1 filter and simulated its magnitude and frequency response using Scilab .  The order of the filter and the Transfer Function were calculated after entering the values of various parameters like : Pass band Attenuation (Ap), Stop Band Attenuation (As), Passband frequency, Stopband frequency. The obtained frequency response was very close to the ideal response. From the obtained characteristics, we verified that, for a Chebyshev 1 filter Pass band : Equiripple Stop band: monotonic No ripples in Passband Lesser transition width, slow roll-off at high frequencies Scilab simulation software made the process of computing Transfer Function of higher order filters and plotting the magnitude and frequency response easier and efficient.    ...
