Voltage controlled oscillator !

These VCO are used in the range of the application as in the communication military industrial and health care markets. VCO is electric oscillator in which output frequency is proportional to its input voltage.An oscillator produced if AC signal frequency to determine by voltages (VCO) are an important factor of a palace locked loop (PLL) if the a reflected signal plls have wide variety of uses the ratio of telecommunication computer and other electronic applicatio. VCO can also have other uses in frequency and other phases modulation and have oscillation such as a function generator.your knowledge for everyone to improve efficiency of electrical engineering tools proof experiments.
