RPN Engineering Calculator™ (REC)

Fo - Geometric Mean Calculator

Click the pale yellow [Fo] button on the Engineering Keypad to launch the Geometric
Mean Calculator. For a detailed description of the Multiple-

Given any two: Center Frequency (Fo), Bandwidth (BW), Lower Band-

As an example let's find the bandwidth and lower bandedge frequency with a center frequency of 35000 Hz and upper bandedge of 36500 Hz. As described in the we start in the Fo text box, input 35000 then press [Enter <—] three times and input 36500 into the FU text box and press [Enter <—] again. Below is the "calculator" after solving the problem.
