dBV to dBm Calculator
This tool converts from dBV/dBmV/dBuV/dBnV to dBm and Watt Enter the dBV value and also the impedance (Z). The default value of resistance is 50 ohm but it can be …
VRMS to dBV Calculator
This tool converts from VRMS (root-mean-square voltage) or simply Volt to dBV (dB Volt). To use the calculator enter the voltage value and use the drop down menu to select …
dBV to VRMS
This tool converts from dBV (dB Volt) to Volt V. Enter the value for dBV and it will give the equivalent RMS voltage. Use the drop down menu to select …
50 Ohm Attenuator Calculator
Most RF circuits are designed for 50 ohm impedance. This tool calculates resistor values to build an attenuator that matches this value of impedance. To use this tool, enter the …
dBm to Amplitude Calculator
In this article we show how to convert from Power in dBm to Amplitude in Volt Referring to the picture of a sine wave above, there are three different Amplitudes …
Frequency Aliasing Calculator (with Practical Examples)
Introduction If a signal is sampled at a rate that is lower than the Nyquist rate, it will be aliased. Calculator Enter the sampling frequency and the input frequency. The …
Nyquist Frequency Calculator
The Nyquist frequency is one-half of the sampling rate. It is measured in samples per second and specified either in Hz/kHz/MHz/GHz or SPS/kSPS/MSPS/GSPS. Enter the sampling rate in the calculator below, …
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 …
