Synopsis: 

Gene prediction is a very challenging problem in the field of medical science. Gene constitute of exons and introns. Exons are responsible for encoding of proteins. The main target of gene prediction is to identify the exons. Gene identification can be done on the basis of property of codon structure that exons exhibits period-3 behavior. To identify the period-3 property, signal processing is used which uses numerical indicator sequences to process the data. This is the reason to convert the characters sequences of DNA sequences into numerical sequences (Binary indicator sequence, paired indicator sequence, real indicator sequence) and then pass through the FIR filter. The present research shows that the FIR filter gives accurate results for selected frequency range.
