LE'ITERS TO THE EDITOR and W I&) =exp ( x cos ot) cos not dot 2 1 -* is the modified Bessel function of the first kind. It must be noted that, in practice, the amplitude can be controlled by R1. In the experimental circuit the different component values are, R =2.7 k, Rc=27 k, RE= 100 k, R1 = 5 k, potentiometer adjusted at R , = 2.81 k, C=lOnF, C 3 = 1 p F , C,=25pF, O.A. = TL 072, T = SC 107.
Using these values in equations (2), it is easily seen that
Consequently, the theoretical oscillation amplitude, obtained solving the non-linear equation (1): is 2.8 V.
The experimentally measured value has been 2-5 V, which is in good agreement with the theoretical value.
