## Instructions

This calculator implements arithmetic operations among impedances using the rules of complex numbers.

Calculation are normally made using impedances “A” and “B” and saving the results in “C”.

Use the copy and paste buttons to save intermediate results in the temporary memory slots MEM1, MEM2, …, MEMx.

## Commands

 A+B → C calculates the complex sum of A and B; writes the result in C A-B → C calculates the complex difference of A and B; writes the result in C A*B → C calculates the complex product of A and B; writes the result in C A/B → C calculates the complex division of A and B; writes the result in C 1/A → C calculates the complex reciprocal of A; writes the result in C A∥B → C calculates A and B in parallel 1/((1/A)+(1/B)); writes the result in C MHz,pF → Z calculates the impedance of a capacitance of given pF at the given frequency MHz; writes the result in Z MHz,µH → Z calculates the impedance of an inductance of given µH at the given frequency MHz; writes the result in Z MHz,Z → pF/µH given the impedance Z and the frequency MHz calculates the capacitance in pF (if X<0) or inductance in µH (if X>0)
