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.
Muzikus.cz Welcome readers! This month, we will begin a three part mini series on analog synthesis. Analog synthesizers like the Minimoog, Arp 2600, and Prophet 5 revolutionized the music of the 1970's as well as being widely used in all genr
Hackaday The two halves of the shell are hinged together and hold a scrap of perfboard for the simple quartz crystal . The prototype was tuned outside the shell, and the 9-volt battery is obviously external, but aside from that it's nothing b
Military & Aerospace Electronics for military RF and microwave applications like radar introduced by GreenrayThe high performance YH1485 OCXO is available from 10 to 100 MHz with +10dBm output, features low phase noise down to -175d
Electronic Design (blog) If we connect a shunt variable capacitor to C6, we can create an with adjustable gain and phase. And we can make that gain and phase shift proportional to an input signal, “modulating” it. Apparently,
Electronics Weekly delivers low phase noiseBased around an atomic clock, the IQRB-2 delivers an accuracy of ±0.3ppb irrespective of temperature fluctuations from -20 to 65°C and operates at a standard frequency of 10MHz with a
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
"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
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.
