Phase modulation with ADAU1701
I need to design a sinusoidal VCO with very deep phase modulation (multiples of 2*PI range). The VCO block under Sources/Voltage Controlled doesn't have phase input, hence I hoped to use trigonometric

On/off keying in Sigma studio (ADAU1787)
Hi all! I am currently trying to get On/off keying working in sigma studio but It really is not going my way. I tried the below scheme. Later I will replace the pulse generator with an input from a MC

VCO Phase Control/Modulation on ADAU1701
Hello all, is there a way to control the phase of a VCO block, in order to have PM (Phase Modulation)? Right now, I am able to create projects with FM which are working perfectly but I would need also

A -1701 FM MPX Demodulator
This is a just-for-fun project, for which no claims are made that it's optimal. I just drew it up in half an hour a few months ago, and then tweaked the thing until it worked. The incoming composite s

Regarding developing a algorithm using sigma studio
I am developing a algorithm for FSK demodulation using ADAU1701 DSP IC without any hardware eval kit. In order to verify my design, I need to give a FSK input to the chip. Is that possible that we can

DSP evaluation board for audio amplitude modulation with 40kHz carrier?
Hi, i'm a student and need some advice in choosing the right and affordable dsp evaluation board. For a project i need to do some amplitude modulation with an audio signal (music) and a 40-45 kHz carr

Intermodulation Distortion with AD1938
I'm working on a project that deals with voice signals and must meet Voice Grade 8 requirements. Most of the requirements are met except for the intermodulation distortion. I'm using an ADAU1442 proce
