One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...
Delta-sigma modulation is a cornerstone approach for high-resolution analogue-to-digital conversion, combining oversampling with active noise shaping to achieve superior signal fidelity. In these ...
Synchronous detection is a measurement method where a stimulus is modulated with some frequency and the response is demodulated to bring the signal back down to base band. Performed when a dc stimulus ...
