Current drawing when in Pulse-Generator mode is about 60µA and 1.2mA when in Signal-Tracer mode operation. Therefore SW1 can be omitted, provided that the earclip or headphones are unplugged when the ...

Accurate 1Hz squarewave pulses are required in stopwatches and other digital circuits. Here is a low-cost, general purpose 1Hz signal generator without using a crystal oscillator. 1Hz signal generator ...

The 4.7uf Capacitor is working as a filter capacitor. The circuit needs fairly high voltage to provide noise at the output. We provided 26V as the input voltage of the circuit. We made the circuit in ...

Circuit Diagram . Working of Sawtooth Generator Circuit. For generating a sawtooth waveform we have used 555 timer IC and LM358 Dual Op-amp IC. In this circuit, we are using transistor T1 as a ...

The triangle wave generator circuit can generate signals with frequencies up to 300 kHz. With the component values presented in the diagram the output wave frequency is 38 kHz. The frequency can be ...

Circuit diagram of the sinusoidal signal generator with forward and inverted outputs, using power amplifier LM272M, is shown in Fig. 1. Besides IC LM272M (IC1), the circuit makes use of +9V voltage ...

The circuit is designed for high analogue signal fidelity (as is, it would need the pulses to be generated with an DAC delivering a signal with appropriate upper and lower signal levels), but dipping ...

The block diagram shows how three low-power audio amplifiers (LM386) are configured to implement a triple-waveform generator at one of two selectable frequencies. The triangular signal goes to ...
