dB to Effective Bits Calculator
This tool calculates Effective Number of Bits (ENOB) in an Analog-to-digital converter (ADC). It uses the dB value of Signal Noise and Distortion (SINAD) and the formula: ENOBbits = (SINADdB …
Signal Processing
Frequency Aliasing Calculator
If a signal is sampled at a rate that is lower than the Nyquist rate, it will be aliased. Enter the sampling frequency and the input frequency. The calculator provides …
Nyquist Frequency Calculator
The Nyquist frequency is one-half of the sampling rate. It is measured in samples per second and specified in Hz/kHz/MHz/GHz which is equivalent to SPS/kSPS/MSPS/GSPS. Enter the sampling rate in the …
Nyquist Rate Calculator
The Nyquist rate [1], is the sampling rate (measured in Hz/kHz/MHz/GHz) equal to twice the highest frequency of a given function or signal. This is the minimum sampling rate to avoid …
What is the Arduino ADC Sampling Rate?
In this post we clarify the sampling rate numbers of the Arduino’s Analog-to-Digital converter. What is Sampling Rate? The sampling rate of an Analog-to-digital converter is the speed at which …
