Signal Calculators

Decibel gain, dBm, Nyquist sampling, FFT bin frequency, SNR, Shannon capacity, duty cycle and more signal-processing tools.

Compute voltage gain G = 20·log₁₀(Vout/Vin) in decibels.

Compute power gain G = 10·log₁₀(Pout/Pin) in decibels.

Convert power P (mW) to dBm = 10·log₁₀(P/1 mW).

Compute the minimum sampling rate fs = 2·f_max.

Compute the frequency of FFT bin k: f = k·fs/N.

Compute SNR = 10·log₁₀(P_s/P_n) in decibels.

Compute max data rate C = B·log₂(1 + SNR) from bandwidth and SNR (dB).

Compute RMS = A/√2 from a sine-wave amplitude A.

Compute duty cycle D = t_on/(t_on+t_off)·100%.

Compute pulse width pw = (D/100)/f from duty cycle and frequency.

Compute symbol rate Rs = Rb/n from bit rate and bits per symbol.

Compute max bit rate R = 2B·log₂(M) from bandwidth and signal levels.
