#PHASE SHIFTER VS SIMPLE DELAY FREE#

In this paper, we present a novel phase shifter topology, which works, at reduced supply voltages, with a very low-power consumption, in the kHz frequency range. INTRODUCTION Phase shifters have been traditionally designed especially with the aim of being applied in RF topologies, such as mixers, modulators, optical communication receivers and oscillators.

The demo version is monophonic only, and a few of the modules that are available in the hardware version are not accessible in the demo, but still, the Nord G2 demo software may just be able to provide you with the tools required to stick your toe in the water.A low‐voltage, low‐power CMOS phase shifter A low‐voltage, low‐power CMOS phase shifterįerri, Giuseppe De Laurentiis, Pierpaolo no support hardware needed other than a half assed capable computer.

It's 100% free (no money needed), and offers a shit ton of capability. You might also give a look/see at the Nord 'G2' demo software. Certainly a hyper powerful learning/experimenting tool if nothing else. That said, I have to wonder if the Nord Modular (any one of them) is capable of doing such a thing? And if not, you would still own one of the most badass VA synths ever made. So obviously that thing is forward most in my mind at this time. I am waiting on the delivery of a Nord Micro Modular, this will be the 5th one I've owned over the decades (I'm keeping this one, by god!). I know that using software wouldn't be as sexy or cool as a hardware solution, however if the whole thing turns out to be a bust, you'll have less money tied up in the project. I have no idea if there are such VSTs offered, but I'd certainly begin my search into this topic there. The classic effect is this allpass setup with some mixing, feedback and a variable lfo that governs the filter center.įor experimenting and learning, I would imagine going with a VST (or perhaps more than one) would be my first instinct. The allpass filters that were mentioned offer phase shift with repect to the frequency range of the phaser, meaning that for a nonperiodic sound the phaser can only shift the periodic parts of the spectrum. This all assums that the signal is periodic, if it isn't than there is no phase with respect to the signal! Some really cool sounds take this form with asymetric transients and usually sound drum-like. I believe the OP didn't ask for any cancellation, the request was very clear for shifting a whole waveform in phase without distorting the waveshape. A phaser combines a phase shifted signal with original one to get notches is frequency response due to cancellation. Mbartkow wrote:People often confuse phase shifting with the function of a phaser effect. For example, a ramp shifted by half of its period (which is the true 180degs) is not the same as ramp inverted. This works only for waveforms that are half-wave symmetric, like a sinusoid. The relationship between phase and time is very easy to understand, once you get this simple example: If you delay a 1Hz sinusoid by 1/8s you get a phase shift of 45degs, but for a 2Hz sinusoid the same delay will give you 90degs of phase shift.ītw, inverting the sign is not equivalent to phase shift by 180 degrees, it is a common fallacy. And such a shift is nothing else than a pure delay - every part of the signal is delayed by the same time (expressed in seconds). The only way to get a phase shift without distorting the wave shape is to shift every spectral component by the amount (expressed in degrees or radians) that is linearly proportional to the frequency, there is no other way. PDO is an oscillator, it does not phase shift an arbitrary input signal, and the OP asked for this. People often confuse phase shifting with the function of a phaser effect.
