Product manual:

NE555 multi-channel waveform generator can generate square wave, sawtooth wave, triangle wave, sine wave.

 

A waveform output is selected by a jumper, and the circuit is simple and convenient to operate.

In the circuit, D1 is an anti-power supply diode and C1 is a filter capacitor. IC1, R1, R2, and C2 form a square wave generator, and the signal is output from pin 3 of IC1, and C3 is an anti-interference capacitor. The square wave output from the third pin of IC1 is divided by R3, R4, and C5. The short-circuit block is shorted to J1 to output a square wave at the output. The other way is divided by C4 and C3, and the sawtooth waveform is formed by J2 through the integrating circuit R5 and C7, and then the next stage integrating circuit R6 and C8 form a triangular wave to output from J3. After the final R7, after the amplification circuit composed of C9, R8, Q2, and R9 is amplified, the collector of Q2 becomes a sine wave. R10, R11, and Q1 form an emitter follower amplifier circuit, and the final signal is divided by W1 and coupled to W1, and output from the output terminal.

 

Circuit principle:

In the circuit, D1 is a diode against reverse connection of the power supply, and C1 is a filter capacitor. 1C1, R1, R2, C2 form a square wave generator, and the signal is output from pin 3 of 1C1

C3 is an anti-jamming capacitor. The square wave output from the 3rd pin of 1C1 is divided by R3, R4 and coupled by C5, and can be output at the output end by shorting J1 with a short-circuit block.

square wave. The other channel is coupled with C3 and divided by C4, and forms a sawtooth waveform through the integration circuit R5 and C7, which is output by J2, and then passes through the next stage of integration.

Road R6, C8 form a triangle wave and output from J3. After ZUI, after passing through R7, it is amplified by the amplifier circuit composed of C9, R8, Q2, and R9, and then at the collector of Q2

into a sine wave. R10, R11 and Q1 form an emitter follower amplifying circuit, and finally the signal is divided by C10 coupled with W1 and output from the output end.
