This sawtooth generator circuit use 741 IC and is used as a musical sound synthesizer. The sawtooth input signal is continously changed through P2 to a waveform with a doubled frequency and half ...

Arduino has taken the product “maker” world by storm and one of the more popular Arduino modules is the Analog Devices AD9851 DDS waveform generator. An Internet Web search for “Arduino DDS” showed ...

A versatile signal generator using Arduino and AD9833 module to produce adjustable-frequency sine, square, and triangle waveforms. Features a rotary encoder for frequency adjustment, dedicated buttons ...

Discover how to produce a multiple output arbitrary signal generator cheaply and quickly with low-cost, hobbyist-level microcontroller development boards. How to create a wide range of complex signals ...

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino and a breakout ...

Last month, I talked about how to get started with mBed and ARM processors using a very inexpensive development board. I wanted to revisit mBed, though, and show something with a little more substance ...

This project is a simple, variable-frequency sine wave generator built on the Arduino platform. It uses Pulse-Width Modulation (PWM) to produce a digital approximation of a sine wave, which is then ...

Abstract: Sawtooth signal at 2.5GHz has been obtained with an RSOA of 1GHz bandwidth. A measured wavelength shifting of 2.5GHz, obtained with the RSOA chirp induced phase modulation, allows 5dB ...
