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.
They were energized directly from the 50 or 60 Hz electrical system. And truth is told the patient would ... The same could be said of the work of Georges Lakhovsky and his multi-wave (MWO). By the 1920s, Lakhovsky had clinics all
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
Sonic State I want to know whether the quality of sound, , filter etc compare with the Sub37 from moog. I'm also curious whether they've got a decent high pass and low pass filter, choice of noise etc.. ring mod, , sample and hold, distortion
PC Authority but this one has some real chops. Co-anded with synthesiser legends KORG, it is what it says on the tin: a basic analogue synth. With keyboard, sequencer, two , an envelope, delay and filter, it has all the important elements of
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 ...
Elektor (blog) A 7 kHz of ~50 mVolts amplitude is fed to a probe put in the solution to measure and the other end of the probe connected to a current to voltage converter with selectable gain. The output voltage is then fed into a RMS conver
Reverb News (press release) (blog) The pattern is the waveform, the number of times per second it cycles is the frequency, which is described in Hz. Human beings can generally hear frequencies between 20Hz and 20kHz, while can cycle well out
"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.
