The circuit was designed to operate with commercially available monolithic programmable counter circuits using TTL
logic, such as MC4016, SN5493 or equivalent. The digital or analog tuning characteristics of the VCO can be used to
extend the available range of frequencies of the system, for a given setting of the timing capacitor C
