Abstract
The utility model relates to a multipurpose pulse generator, which is composed of a switch, a current limiting resistor, a pressure-reducing potentiometer, a charging capacitor, a light-emitting class diode, a boosting transformer and an output potentiometer, which are electrically and sequentially connected. The utility model is characterized in that the positive electrode of a battery is connected in parallel with the positive electrode of the light-emitting class diode on the positive electrode of the capacitor by passing through a series circuit which is composed of the pressure-reducing potentiometer and the current limiting resistor after passing through the switch, the negative electrode of the battery is connected with one end of the primary electrode of the boosting transformer and, the other end of the primary electrode is simultaneously connected with the negative electrode of the battery and the negative electrode of the capacitor; both ends of the secondary electrode of the transformer are connected in parallel with both ends of the output potentiometer, and the central head of the potentiometer and the other end of the potentiometer form signal output. The multipurpose pulse generator is a good tool used for testing the low-frequency characteristic for radio lovers, the cost is low, and the utility model is widely used for the fields of medical treatment, tests, experiments, etc.
Description
It is a kind of simple and easy multipurpose pulse generator that the utility model relates to, and it is a kind of good tool that the radio amateur tests low frequency characteristic.
At present, known pulse generator: 1, be complex circuit.2, be the cost price height, make the radio amateur of general low income be difficult to buy.
The purpose of this utility model provides a kind of simple and easy multipurpose pulse generator, and it only just has been made of 7 main components and parts, and cost is low and can also use widely in fields such as medical treatment, test, tests.
The purpose of this utility model is achieved in that after anode passes through switch passes through the series circuit that step-down potentiometer and current-limiting resistance are formed again, in the luminous class diode cathode of capacitor anode and connect, its negative pole connects the elementary end of step-up transformer, the elementary other end is connected simultaneously with the battery cathode capacitor anode, the transformer secondary output two ends are connected on output potential device two, and its center head and the other end are signal output.
Owing to adopt such scheme, just can only just constitute a kind of simple and easy, convenient multipurpose pulse generator that uses with 7 components and parts commonly used.
Below in conjunction with accompanying drawing and enforcement the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is a multipurpose pulse generator embodiment schematic diagram.
Mains switch among the figure; 2, step-down potentiometer; 3, current-limiting resistance; 4, charging capacitor; 5, luminous class diode; 6, step-up transformer; 7, output potential device.
In Fig. 1: switch (1), step-down potentiometer (2), current-limiting resistance (3), be serially connected with on the positive source, current-limiting resistance (3) other end and capacitor (4) are anodal, luminous class diode (5) positive pole joins, negative pole is connected with the elementary end of step-up transformer (6), and the elementary other end power cathode of transformer (6) joins in the lump, two of transformer secondary output two and output potential device (7) joins, and its center head and the other end are output signal.
In example shown in Figure 2, step-down potentiometer (2), output potential device (7) is the plastics knob, and luminous class diode (5) is a shades of colour, and mains switch is miniature (1), can install miniature external power supply in the both sides of box, the signal output plughole.
