This Design Idea provides a simple, inexpensive, portable circuit as an alternative to a microcontroller to provide a wide-range source of low-distortion sine waves for audio-circuit design and debugging. Although sine waves from DDS (direct digital synthesis) offer greater stability and fewer harmonics and other spurious-frequency components, this more `retro` approach lets designers use Linear Technology Corp`s LTSpice freeware and hone their circuit-simulation skills.
Hackaday The problem is, the isn't perfect. And the other components will have little issues. If you've ever tried this in real life, you'll find that when the is right at the 2.5 V mark the output will probably swing back and forth before

EDN Europe (registration) (blog) moduleBased around an atomic clock, the IQRB-2 delivers an accuracy of ±0.3 ppb irrespective of temperature fluctuations from -20 to 65°C and outputs a standard frequency of 10 MHz with a 50&O
With his usual impeccable handwriting and schematic drawing skills, [GreatScott!] documents that his CCFL inverter is a resonant Royer producing a of about 37 kHz, which is then boosted to about 2400 volts. That's pretty good, but ...
Hackaday All the actions of its microprocessor will be governed by a crystal , which while it won't be caliated to an incredible standard will still be good enough for the purposes of a free mobile phone instrument. Even if we can't entirely
MusicRadar.com ... both) frequencies allows the creation of new tones - from harmonic purity to clangorous nastiness. Both can have their frequency modulated by a sine or square wave LFO (there's a dedicated knob to set the LFO speed/freque
"With FM synthesis, at least two table lookup are used in combination, but the phase part is not distorted like it is in PD. The output of one 'modulator' modulates the frequency of the other one (the 'carrier
RF Globalnet (press release) Clock Featuring High Frequency And Ultra Low Phase ...Crystek Crystals Corporation has launched the CCSS-945 – a True Clock (XO) providing -170 dBc/Hz noise floor at 1 MHz offset. The close-in phase
For our use here, we will create an signal source that can produce three waveforms / wave shapes: , square wave and sawtooth wave. Each of these wave shapes has characteristics that make it suitable for use in electronic music.
