Help

Computes resistor values for pi and T attenuators, and converts voltage/current ratios and or power ratios to and from DB.
Enter any of the above values, along with the source and load impedance, and read the resistor values for the attenuators.
The minimum value of attenuation is also displayed for the source and load impedance given, allowing you compute the values for 2 resistor minimum loss pads by transfering this value in Row 1.
