An analog filter removes the high-frequency distortion that's generated in the resulting square wave, and the result—thanks to Nyquist again—is the original signal in analog form.

Application examples using tools that emphasise graphical capture and exploration. Andrew K. Betts, Daniel Saias, Hervé Guegan, Nicolas Delorme Asygn, France Abstract — Today’s on-chip ...

To convert from analog to digital, the analog signal first is sampled at a carrier frequency. For a given sample period, the area under the analog signal equals the area under the PWM pulse.

For AC signals above the audio range, you may need a microcontroller that contains an SAR (successive-approximation register) ADC, which can sample at rates of 1 Msample/s (see “ Inside an SAR-type ...

Analog-to-digital converters (ADCs) used in analog-signal measurement systems may experience multiple inaccuracies, which lead to errors in those systems. Understanding how this happens can help ...

Addressing a major roadblock in next-generation photonic computing and signal processing systems, researchers at the Harvard ...

ADC’s Converting analog to a digital format involves tradeoffs: how often you need to be updated as to the signal (sample rate), how much you need to know (resolution), and the cost (how much ...

Analog Devices is aiming at low-power signal measurement with a combined synchronous demodulator and filter chip which allows precision magnitude and phase measurements to be made on analogue signals ...

The rise of 3D integrated circuits (ICs) and heterogeneous packaging is reshaping how automotive ICs fulfill demanding analog ...
