Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Maximum frequency

Required number input.

Calculate the minimum sampling rate for perfect reconstruction of a bandlimited signal. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Nyquist rate

The resulting nyquist rate returned as a number.

• The Nyquist criterion assumes a band-limited continuous signal and an ideal sampling model. Real systems need transition bandwidth, anti-alias filtering, clock quality, aperture behavior, and spectral guard bands; sampling exactly twice the highest nominal frequency is rarely sufficient.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Alias Frequency

  Calculate the aliased frequency produced by sampling a signal above the Nyquist limit.

• Jitter SNR Limit

  Calculate the signal-to-noise ratio ceiling imposed by sampling clock aperture jitter.

• Nyquist Frequency

  Calculate the highest frequency that can be represented without aliasing at a given sample rate.
