Signal Processing Calculators

Filter Designer

Design passive RC and LC Butterworth low-pass, high-pass, and band-pass filters. Calculates component values (C, L), time constant, and attenuation for filter orders 1 through 4.

Nyquist Sampling

Calculate Nyquist sampling rate, oversampling ratio, aliasing frequency, ADC dynamic range, SNR, and data rate. Verify that your sampling rate satisfies the Nyquist criterion and avoid aliasing in your system.
