A signal-to-noise ratio (SNR) lets us express the relationship between signal and noise powers, as well as between the root-mean-square (rms) values of signal and noise voltages: SNR (dB) = ...

Figure 1. Noise in the signal chain. A noise budget is the allocation of the noise in a signal chain that results in an acceptable signal-to-noise ratio (SNR) at the output. The SNR is defined as the ...

What's required in a source for mixed-signal test. Key factors in achieving low distortion. Designing a signal-generation path. What is digital predistortion (DPD)? Using LDOs to power the test system ...

The BlasterAmp [1] has proven useful to me in testing all sorts of analog-to-digital converter (ADC) circuits, even my digital oscilloscopes. While I mainly conceived it to test integrated ADCs in ...

Choosing a drive involves several design factors that depend greatly on the task at hand. This top 7 list will guide you, whether your task requires precise and exact movements... Actuators with ...

Learn how ECG noise filtering that adapts to noise type improved QT and QRS accuracy and supports more reliable cardiac ...

Level-crossing analog-to-digital converters (LC-ADCs) represent an innovative approach to signal digitisation that departs from conventional uniform sampling. Instead of capturing signals at fixed ...

Noise is the real enemy of data communications. Whenever electrons travel over a wire or radiate through space, they generate some electromagnetic noise. Therefore, whenever a data signal is sent ...
