Coil Calculator
Version 1.0 of the "Electronic Calculation Program". Smaller but no less useful than V2.0 in most ways.
Version 2.0 the "Electronic Calculation Program" is a Windows program that performs several RF and one amateur radio calculation. Version 1.0 of this program just calculated values to conjugately match a transistor using either S or Y parameters as described in "RF Circuit Design" by Chris Bowick. Version 2.0 still includes this function plus several other calculations using S or Y parameters from the same book. However, Smith chart plotting is still necessary. Version 2.0 will also calculate Butterworth filter component values using either a known attenuation or number of circuit elements.
