Abstract
Apparatus for generating noise is described incorporating means for generating a noise frequency spectrum, a plurality of voltage controlled oscillators and means for coupling the voltage controlled oscillators to an output. The invention overcomes the problem of a single voltage controlled oscillator which could not slue and settle at an appropriate frequency prior to being coupled to an output which resulted in undesired frequencies being generated during this slueing and settling time.
