1Hz to 10MHz Sine/Square Function Generator based on the AD9835 & PIC16F628 -  An extremely simple and low cost Sine/Square wave generator based on the Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip. The frequency can be set for any frequency from 1Hz to 10MHz in 1Hz resolution steps! All this with three push buttons and a novel "sliding window" LED display. The controller chip is a Microchip PIC16F628. There is no wiring, and the PCB fits into a standard UB3 Jiffy Box. . . .  

1Hz up to 22MHz Generator -  This is simple MAX038 generator. It produces sine, triangle and square waves from 1Hz up to 22MHz. The Amplitude, offset and duty cycle are adjustable to offer wide range of generated signals. Frequency adjustment is made as a rotary switch S8 with a capacitor bank and variable resistor P7. . . .  [Designer's name not given]

20MHz Function Generator -  The High Speed Function Generator was published in the professional electronics section of the Aug 1996 issue of Electronics Australia, and has proven to be extremely popular. It is capable of generating 20Mhz Sine, Square, Triangle, and TTL waveforms. . . .  

20MHz Function Generator 2 -  MAX038 0. 1Hz, 20MHz. . . .  

20MHz Function Generator 3 -  Uses MAX038 IC to provide 0. 1Hz, 15MHz sinusoidal, square and triangle frequency. . . .  

20MHz High Speed Function Generator -  The High Speed Function Generator was published in professional electronics section of Aug 1996 issue of Electronics Australia, and has proven to be extremely popular. kit is no longer available from any ofkit suppliers. . .  

68HC11 Function Generator -  This site contains complete schematics and code for a 68HC11 based frequency counter, square wave synthesizer, sine wave synthesizer, programmable filter, capacitance and inductance meter, with a digitalker speech synthesizer output. Project specifications are given below. . .  [by Michael Ellis]

68HC11 Instruction Halts External RC Clock -  04/27/95 EDN Design Idea   Using the circuit in Fig 1, a 68HC11 P's stop instruction can put the P's external RC-oscillator clock, as well as the P itself, into a low-power mode. On receiving an interrupt, the P will exit the stop condition and enable. . .  [by Allen Harstine, Micro Systems Engineering Inc, Lake Oswego, OR]

8038 Function Generator -  Built around a single 8038 waveform generator IC, this circuit produces sine, square or triangle waves from 20Hz to 200kHz in four switched ranges. There are both high and low level outputs which may be adjusted with the level control. This project makesa useful addition to any hobbyists workbench as well. . .  [Andy Collison, designer]

8038 Generator -  ICL8038 signal generator chip, manufactured by Intersil. An improved version, made by Exar corp. is available (XR8038A). It can be used to produce three types of waveforms, sine, square and triangle. The frequency, amplitude and duty cycle can be varied, and selection of waveform is done digitally. To further reduce the complexity, a 3-to-1 switch may be used in place of the digital selection circuitry. I made use of the digital selection mechanism because switches available on the market are prone to dirt accumulation and poor contact quality. Besides, the digital method is a lot cooler!. . . .

AN-322: Improve Function Generators with Matched D/A Converters -  AN-322 Analog Devices App Note - AD7528 Dual 8-Bit CMOS Multiplying DAC Makes Function Generation Practical and Affordable. . .  

DDS Function Generator -  The function generator is a generic measurement equipment to generate test signals. Most function generators can generate a sine, square and/or triangle wave and high end equipment support arbitrary waveforms and have multiple channels. The simple. . .  [Designer's name not given]

DDS Function Generator -  This is a new implementation of the AVR DDS signal generator v2. 0, already published in scienceprog. com. It is obvious that full credit for the original schematic and the firmware goes to its original creator. Presented here is a different PCB that. . .  [Designer's name not given]

Function Generator -  A function generator using the ICL8038 integrated circuit. Is has four ranges and capable of sine, square and triangle outputs. . . .  [Andy Collison's website]

Function generator -  Function generator by NE566. . .  [Name of Designer is not included]

Function Generator -  After the recent demise of our multifunction signal generator, we decided to make one of our own. The circuit uses a PIC16F870 (about $3) , an R/2R resistor ladder network (for a real fast and cheap D/A) , and a few other parts. . . .  [by Luhan Monat-Mesa Arizona]

Function Generator -  Built around a single 8038 waveform generator IC, this circuit produces sine, square or triangle waves from 20Hz to 200kHz in four switched ranges. There are both high and low level outputs which may be adjusted with the level control. This project makes a useful addition to any hobbyists workbench as well. . . .  [by IQ Technologies Industry, unless otherwise noted online]
