Development of a Technique for Restoring the Fidelity of Distorted Playback Audio Signal from Analog Cassette Tape

A. O. Atijosan, S. A. Adeniran, M. O. Sokunbi & R. A. Badru · Current Journal of Applied Science and Technology · 2015

A simple yet elegant analog based technique for restoring the fidelity of playback audio signals emanating from magnetic cassette tapes is presented. The technique makes use of information from the high frequency bias signal in magnetic cassette tapes to correct for errors in the...

Development of an Error Correction Technique for Audio Signals Recorded on Optical Compact Disk

A. O. Atijosan, S. A. Adeniran & R. A. Badru · Current Journal of Applied Science and Technology · 2015

The occurrence of high random bit error rates alongside long burst errors in playback audio signal recorded on compact disk (CD) poses a problem beyond what the usual Cross Interleaved Reed-Solomon Code (CIRC) may handle. In this paper we propose a technique that makes use of the...

Effective Earth Radius Factor Prediction and Mapping for Ondo State, South Western Nigeria

A. O. Atijosan, R. A. Badru, K. H. Muibi, S. A. Ogunyemi & A. T. Alaga · Journal of Scientific Research and Reports · 2015

Accurate prediction and determination of the effective earth radius factor (k-factor) is critical for optimal performance in the design and planning of terrestrial line of sight communication links. In this work an artificial neural network (ANN) model is developed and used to pr...
