Embodiment Construction
[0075] For ease of understanding and brevity, we will take the electrical schematic diagram Figure 2 as a basis, combined with the overall block diagram figure 1 and the corresponding waveform image 3 and other corresponding figures to illustrate the specific implementation.
[0076] The integrated circuit 100, transistors 201, 202, potentiometer 300, resistors 301, 302, 303, 304 and capacitors 501, 502 together form a self-excited multivibrator. Pin 3 of integrated circuit 100 outputs a square wave, and pins 2 and 6, which are connected to the collectors of transistors 201 and 202, capacitor C502 and the base of transistor 203, output a triangular wave with good linearity. Transistor 201 is a charging current source, and transistor 202 is a discharging current. source, the charging current is adjusted by the potentiometer 300, which also changes the duty cycle of the natural frequency and waveform. Capacitor 502 is a triangular wave forming capacitor, 501 is a surge smooth...
