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 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
An audio is the other tool required for this exercise. The best I've found is the Potomac Instruments AG-51 Audio Generator. It was designed in the days when stations were required to do annual audio proof of performance ...
EDN Europe (registration) (blog) To ensure a smooth frequency slope, IQD's new analogue ASIC based IQXT-274 Temperature Compensated Crystal (TCXO) is tested using one frequency reading every 2 degrees C over the full operating temperature ra
Market 2016 Analysis and Forecast to 2021This can be accomplished in a simple clock or crystal , a TCXO (resulting in a TC/VCXOtemperature compensated voltage controlled crystal ), or an oven controlled type (resulting in an OC/VCXO-oven c
MusicRadar The VA can run in Morphing (fully adjustable between triangle and pulse) or Sine ( with adjustable waveshaping) modes, and both can be set to reset their phase with every incoming note or not. The sample provides sub
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
MusicRadar.com If you have multiple , don't be afraid to use them. To learn what they all do, start experimenting by duplicating the first settings to the second, then adjust the second. Try detuning it slightly to thicken up a sound, or
MusicRadar.com "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.
