75 Ohm Attenuator Calculator
Many RF circuits for audio and video systems are designed for 75 ohm impedance. This tool calculates resistor values to build an attenuator that matches this value of impedance. To …
dB Attenuator Calculator
To use this tool, enter the desired value of dB attenuation and the characteristic impedance (default value is 50 ohm). The tool computes resistor values in different configurations: Pi Attenuator …
dBV to V RMS Calculator
This tool converts from dBV (dB Volt) to Vrms (root-mean-square voltage). Units are Volt/millivolt/microvolt/nanovolt RMS. Formula VRMS = 10(dBV / 20)
40 dB Attenuator Calculator
Use this tool to calculate Resistor values for a 40 dB Pi Attenuator circuit. 40 dB is the default attenuation value below and the characteristic impedance is 50 ohm. Both …
20 dB Attenuator Calculator
Use this tool to calculate Resistor values for a 20 dB Pi Attenuator circuit. 20 dB is the default attenuation value below and the characteristic impedance is 50 ohm. Both …
