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.
