Square wave generator Circuit Diagram This function generator a.k.a waveform generator can produce square wave (5V/0V) with frequency ranging from 1Hz to 2MHz, the frequency of the wave can be controlled by a knob and the duty cycle is hardcoded to 50% but it is easy to change that in the program as well. Apart from that, the generator can also produce since wave with frequency DIY Function/Waveform Generator: In this project we will have a short look at commercial function/waveform generators in order to determine what features are important for a DIY version. Afterwards I will then show you how to create a simple function generator, the analog and digital way. Step 3: Build the Circuit! Here you can find the The bridge circuit is C1 R4a and C3 R4b. R4 is a dual-ganged potentiometer and controls the frequency, which is 1/2ฯRC. Assuming R4 is central, say 2k, this would be 1/(2*ฯ* 5k * 0.01u) = 3kHz. The lamp is a small 12V incandescent light bulb.As the filament heats up, its resistance goes up, reducing the current through it, reducing the gain and amplitude at the output, so you have a very
The below indicated sine wave generator circuit is not only easy to build, it also provides an exceptionally pure output having a total noise and distortion level that is effectively under 0.1%. The design is a simple Wien Bridge oscillator configured around an operational amplifier.
ICL8038 Function Generator Circuits Circuit Diagram
Today we will be using the ICL8038 voltage-controlled oscillator, or precision waveform generator, to create four function generator circuits. The ICL8038 can generate three output waveforms without many external components: a sine wave, a triangular wave, and a square wave.

How to Build Your Own Function Generator Using Analog Devices' AD9833 Circuit Diagram
This simple waveform generator circuit consists of a single TTL 74LS14 Schmitt inverter logic gate with a capacitor, C connected between its input terminal and ground, ( 0v ) and the positive feedback required for the circuit to oscillate being provided by the feedback resistor, R. So how does it work?. Assume that the charge across the capacitors plates is below the Schmitt's lower
