On the simplified implementation of quadrature oscillator models and the expected quality of their operation as VCO´s

This communication discusses mathematical systems which are found to be appropriate for the electronic implementation of simplified (and of a relatively cheaper realization) oscillator models for generating sine waves in quadrature. It is shown that in spite of the simplification, the operation of the oscillators as VCO´s is expected not to be degraded and the amplitudes stay precisely stabilized.
