Sai Venkatesh Balasubramanian · viXra · 2015
In the present work, the solitary chirplet, formed by modulating a frequency modulated signal with a hyperbolic secant envelope is formulated. It is seen that this solitary chirplet possesses a high number of vanishing moments. Sample analysis of sinusoidal and FM signals using the solitart chirplet confirms its efficacy in detecting frequency changes and discontinuities, following which the analysis of an earthquake signal is presented. It is seen that the proposed solitary chirplets come in handy while analyzing frequency variations and breaks in signals.
