Understand subtraction frequency circuit design. (2) Content: Analysis of cases of 2.8 procedures principle, the simulation results are given to illustrate the function statement. Can change the process of division ratio. Pin lock can refer to Figure 2.9. (3) Description: CLK2 jumpers will take on even in 2Hz. LED1 instructions input frequency, LED2 hours after the results of frequency. LED1 flashes can be seen every 6, LED2 flashing a little bit, since the frequency of 6 minutes circuit.
