Rebuttal to 'Fully-uncoupled independent control of frequency and condition of oscillation: A caution'

Based upon the experimental results of the two CFOA-based fully-uncoupled sinusoidal oscillators proposed earlier by Bhaskar-Gupta-Senani-Singh, recently Abuelma'atti and Khalifa issued a caution that the classification of this class of oscillators providing independent control of condition of oscillation (CO) and frequency of oscillation (FO) through separate elements, as fully-uncoupled, does not appear to be correct. In this communication, we present the results of a recheck of the experimental data of Abuelma'atti and Khalifa and show that their experimental results are not repeatable and in most of the cases, the oscillations do not even exist and hence, the measurement data as given by them is misleading. Furthermore, it is shown that the measured oscillation frequencies, as shown by Abuelma'atti and Khalifa in four tables, do not tally with those calculated from their own formula as well as the experimental results taken by us. This communication thus, refutes the claims made in the quoted paper of Abuelma'atti and Khalifa published in this journal earlier.
