PURPOSE:To facilitate the conversion of clock frequecy with a simple circuit, by using two NAND gates, a specific frequency and a clock signal of an integer-fold level of frequency compared with said specific frequency. CONSTITUTION:A clock signal of frequency f is supplied to an input terminal 11 of an NAND gate 10; while a clock signal frequency Kf (K: an integer) is supplied to an input terminal 13 of an NAND gate 9. While a signal of L level is applied to a terminal 14, the output of the gate 10 is equal to the clock signal supplied to the terminal 11. When a signal of H level is applied to the terminal 14, the output of the NAND gate is turned to a clock signal of frequency Kf. As a result, the output of the gate 10 is turned to a clock signal of frequency nf. |
