Title: Oscillating circuit
Inventor: YAMANE ETSUO
IPC: H03J7/06
Filed: 1982-01-18
Abstract: PURPOSE:To fix an oscillating circuit to a desired oscillation frequency at a high speed with high precision by use of a microcomputer mu-COM. CONSTITUTION:When the desired oscillation frequency is inputted from a keyboard 5, the mu-COM4 supplies gate time shorter than normal gate time to a counter 3, which counts the oscillation frequency of an oscillating circuit part 1; and its counted value is compared with the desired oscillation frequency and signals are outputted to terminals up and Df until their difference enters a predetermined range. Consequently, transistors (TR) Q5-Q7 are driven and a capacitor C4 is charged or discharged rapidly through low resistances R9 and R13 to vary the oscillation frequency of the oscillating circuit part 1 approximately to the desired oscillation frequency at a high speed. Then, the mu-COM4 supplies the normal gate time to the counter 3 to output signals to terminals (u) and D, and consequently TRs Q2-Q4 are driven to charge or discharge the capacitor C4 slowly, obtaining the desired oscillation frequency.
