    Waveform Generator 2025-01-11

    AD9833 module is a 0-10Mhz waveform generator with integral 25MHz crystal oscillator, the output frequency is set by the SPI controlled divider of the AD9833. A DAC shapes the sine and triangle waveforms, amplitude is 600mV. Squarewave amplitude is 5V. The PIC drives the AD9833 using SPI. The...

    odd signals from transimpendance amplifier

    I am building a setup to be able to read the reflected light from a laser beam with a photodiode, which I have never done before. so I bought this photodiode and this transimpendance amplifier. But after wiring it up, I didnt get any useful readings from the TIA. So I I reduced the voltage from...

    How to build this kit? [AVR DDS Function DDS Signal Generator]

    Hi guys. Recently I have found an electronic kit at home that I bought on eBay some months ago. I have no idea how to start building it because as far I can remember I have not instructions and also no experience at all. I have been searching on my email to know where I bought it and I checked...

    Analog Signal Generator Design

    I want to design an Analog Signal (0 to 10V DC) Generator. I am new to circuit design. I need help to design and manufacture this device. It will be very helpful if you can point me in the right direction. I tested this circuit with a Arduino Mega board and generated upto 5V, but the resolution...

    Variable high frequency conversion from 50-60 Hz to HF?

    The wall power is rated at 50 to 60 cycles per second. I want to feed a circuit with that energy (50 - 60 Hertz) and obtain a higher frequency output, pure sinusoidal wave. Preferably, it can be tuned from around 100 hertz to 30 kilohertz. The output wattage must be at least 300 watt.
