Abstract

PURPOSE:To enable the frequency adjustment easily, by selectively cutting off and removing the leads for a part of a plurality of fixed resistors, in the CR oscillation circuit which can simply adjust frequencies. CONSTITUTION:The resistance value R0 is selected together with the value of the capacitors C1, C2 so that the required oscillating frequency can almost be obtained. Further, the resistors R1, R2 are selectively cut off and removed in the stage of adjustment according to the frequency to be finely turned. Thus, the adjustment can be made easy.
