Patent ID: 7692419

Claim:
A system for measuring signal frequency, said system comprising: a frequency amplification component configured to access an input signal of a first frequency and generating a modified input signal of a second frequency; a frequency counter coupled to said frequency amplification component, said frequency counter operable to access said modified input signal and measure a quantity of counts during a gate time of said frequency counter, wherein said quantity of counts relates to said second frequency of said modified input signal; a logic component coupled to said frequency counter configured to receive a measurement of said quantity of counts, wherein said logic component is operable to determine said first frequency based upon said measurement of said quantity of counts; and, a control component coupled to said frequency amplification component, said control component configured to increase an amplification factor by which said first frequency is amplified to produce said second frequency, and wherein said amplification factor is automatically determined such that said second frequency has a maximized value between said first frequency and an allowable maximum frequency.
