This calculator helps you determine the values of the resistors R1 and R2 to be used for a bridged-tee attenuator.
This balanced attenuator calculator helps you determine the resistor (R1) values for a balanced attenuator.
Early in my explorations of electricity, I came across a length of…
A Link Budget puts into account all gains and losses a signal goes through in a system as it is transmitted. The calculator calculates the power of the received signal given amplifier and antenna gains, and medium loss.
This calculator will determine the correct antenna downtilt angle given the heights of the antennas and distance between them.
What voltage will you choose to use for each of the station batteries?
This tool is designed to calculate the maximum distance (range) that a radar can detect
A helpful tool for computing the Effective Isotropic Radiated Power (EIRP) of an antenna
Given three of the four input parameters (refractive indices, angles of incidence, and refraction) this tool calculates the missing variable based on Snell's law.
In very simple, qualitative terms, rate the impedance of capacitors…

This calculator will compute the required resistor ratio (R2/R1) and reference voltage (VREF) to create the desired high (VTH) and low (VTL) threshold voltages in a non-inverting comparator circuit with hysteresis (commonly called a Schmitt trigger).
This calculator shows the peak-to-peak voltage (VP-P) value from the peak voltage, RMS voltage, or average voltage.
At first it may seem pointless to have the four buffer gates following…
