PURPOSE:To make the use of an oscillator easier, by splitting a capacitor being a time constant of a multivibrator into two, inserting a resistor to the emitter of a transistor (TR) between the capacitors, and varying the inserted resistor. CONSTITUTION:A capacitor being a time constant between a base of a TR1 and a resistor 2 at a collector side of a TR opposite to the TR1, is split into two to form a capacitor 4 of the collector of the TR1 and a capaitor 5 at the base. A resistor 6 is inserted between the splitting point of the capacitors 4 and 5 and GND at the emitter side of the TR1. The oscillating frequency is changed by varying the resistance value of the resistor 6. |
