Quadrature modulation can be used to implement an endless number of modulation schemes, but it has the most value for digital modulation. For example, digital modulation using the phase of the vector ...

In Tone2’s latest Icarus synth (pictured left), for example, modulation sources include the synth’s three onboard LFOs, its four envelopes, and external sources like MIDI information (the velocity of ...

This tutorial explains the fundamentals of time-, frequency-, and modulation-domain analysis from the perspective of several examples.

See modulation and carrier. Vary the Amplitude In AM modulation, the voltage (amplitude) of the carrier is varied by the incoming signal. In this example, the modulating wave implies an analog signal.

He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.

High modulation depth (>7 dB) is preferable for most applications (for example, high data-rate interconnects and high-sensitivity sensing); however, <∼ 4 dB modulation depth can be adequate for ...
