One as shown in Figure 5, is single cycle frequency measurement principle schematic; Tin in a complete cycle of input signal, the times N r that the upper limb of counting reference signal climbs, the cycle T in that can calculate input signal is:
Tin＝Nr/fre，
Therefore, frequency f in to be measured can be:
fin＝fre/Nr，
Taking the frequency f re=100MHz of reference signal as example, the periodic error of counting is Δ t=1/fre=10ns, measures error ratio and is not more than 1% if order frequency, and the cycle of input signal should be greater than 1 μ s, that is the frequency of signal to be measured should be less than 1MHz.
Its two, as shown in Figure 6, be multicycle frequency measurement principle schematic; In Nin complete cycle of input signal, the times N r that counting reference signal upper limb climbs, the cycle T in that can calculate input signal is:
Tin＝Nr/Nin*fre，
Therefore frequency f in to be measured can be:
fin＝Nin*fre/Nr，
Now the periodic error of counting will be reduced to 1/Nin, and therefore the frequency of maximum signal to be measured can be increased to Nin doubly.
Its three, for the time that unified frequency each time measures, as shown in Figure 7, be timing frequency principle of measurement schematic diagram; Be 1 second if set the measurement time, count reference signal pulse wave upper limb and trigger in fre time, the times N in that input signal pulse wave upper limb occurs is the frequency of input signal, and now frequency measurement resolution is 1Hz; If 10 times of measurement time decreased are set as to 0.1 second, frequency measures resolution and falls 10 times and be 10Hz.Therefore, can be according to the frequency range of input signal, coordinate frequency measures resolution and measurement time.
