If I'm wrong, can someone please correct me? This calculator is used for calculating unbalanced attenuator. By adding a balanced leg to the attenuator circuit (and additional resistors into that leg), should not the resistor values be R/2? Otherwise, will not the balanced attenuator board, calculated above as an unbalanced circuit, become a 20K attenuator due to (+RT) + (-RT) = 2*RT? (+RT) and (-RT) being the balanced leg terminators of the circuit. (10.2K + 10.2K = 20.4K) Soren, Thanks for putting this GB together. I'm looking forward to getting my boards. Now, just to figure out the resistors.
