Resistor Coder v.1/16/1999
Resistor Coder calculate the resistance in ohms of any resistor color code entered into its input section. Four or five band resistors can be accommodated by this program.
Pi Filter Designer v.1
Pi Filter Designer is a simple 3 element 50 ohm input and output impedance pi filter designing application,
NPN DC-BIAS v.16
Voltage divider bias NPN bipolar transistor amp design. NPN DC-BIAS calculates the various voltages and currents of a simple voltage divider bias NPN bipolar transistor amp. The following is calculated: IB, IC, IE, VE, VB, VC,
HF Dipole v.2
Calculates the length of each leg of a 1/2 wave wire dipole antenna. HF Dipole is a very basic software for calculating the length of each leg of a 1/2 wave wire dipole antenna. Program good for 1 - 500 MHz, although intended for MF - HF useage.
Ferrite v.1/19/1999
Ferrite is used to calculate the number of turns required on toroidal ferrite cores to achieve the desired millihenry-value inductance. 15 different ferrite toroids are included in this application.
CoilBuilder_99 v.4
CoilBuilder_99 is a powdered iron inductor winding application. Enter desired inductance, select core size and mix and press the Calculate button to determine the correct number of windings for your inductor. Data is also given showing, core color,
CapCoder v.07/02/1999
CapCoder gives the capacitance in microfarads, nanofarads, picofarads, and tolerance of any capacitor code entered into its input section.
Capacitor Coder v.07
Performs capacitance calculations. Capacitor Coder calculate the capacitance in microfarads,
