Calculators
To supplement our course material, a series of calculators are being developed that we
hope will be useful. These calculators will all be listed here as they are developed.
If you have any suggestions for any calculators that you would like to have us develop,
let us know at webmaster@learningmeasure.com,
and we will add it to our list of calculators to be developed.
General
Electrical Engineering
- Ohm's Law Calculator - Given any two of Resistance, Voltage, Current, or Power, this computes the other two.
- Resistor Color Code Calculator - A javascript resistor color code calculator
- dB Ratio Calculator - Given any of dB Ratio, Power Ratio, or Voltage Ratio, this computes the other two.
- Friis Transmission Equation - Determines the power coupling between two antennas
- Reflection Calculator - Converts between impedance magnitude, reflection coefficient, return loss, and VSWR
- Cascade Noise Figure Calculator - Computes the noise figure of two cascaded 2-ports. Can be used
with more than two stages, as the result of one calculation becomes the first stage for the next calculation.
- Rectangular Waveguide Mode Calculator - Calculates the cutoff frequencies of the TEmn and TMmn modes
for m,n<6.
- Rectangular Waveguide Guide Wavelength Calculator - Calculates the guide wavelength of the TEmn or TMmn modes for the frequency of interest.
- T Attenuator Calculator - used to determine the resistance values required for a T attenuator given the desired attenuation, input impedance, and output impedance.
- Pi Attenuator Calculator - used to determine the resistance values required for a Pi attenuator given the desired attenuation, input impedance, and output impedance.
