Nonlinear tunning characteristic of Voltage Controlled Oscillator block





This block computes an hyperbolic tangent function. The output of this block is given by the following expression :

y=F\left(u\right)=\alpha \tanh\left(\beta u\right)

with Remember that tanh() is the hyperbolic tangent function defined by :


In fact the output of this block provides a frequency deviation depending of the input voltage. The Fig.1 shows an example of this static function.
