Abstract
PURPOSE:To ensure an easy conversion for the frequency in a simple constitution by reading the FF output signal by the conversion signal applied to the clock input of the register and sending the digit output to the OR gate with every second register at least. CONSTITUTION:Converted signal S1 is supplied to clock input T of FF12, and its reverse Q output Q' is supplied to the data input D as well as to serial input INS of shift register 13. Here register 13 reads the output signal of FF12 according to conversion signal S2 supplied to clock input T, and OR gate 14 is provided to give the OR input for the digit output of at least every second order of register 13. Thus signal SO which is synchronized with signal S2 and then converted signal S1 into the fixed ratio is delivered. In such way, the frequency can be converted easily in a simple constitution.
