HF Filter Design and Computer Simulation

This appendix defines equation variables (symbols) used throughout the book. These variables are listed in this appendix in alphabetical order. This appendix also briefly describes =SuperStar= circuit file model codes and variables written by the =M/FILTER= program to define physical dimensions of distributed filter structures. Model codes are organized by process and by function. Circuit file dimensional variables are listed in alphabetical order.
When possible, equation variables (symbols) are defined consistently throughout the book. In certain cases, the original contributor's definitions are retained to avoid reformulation of the original equations. This introduces some unavoidable inconsistencies. In general, definitions are obvious if a chapter is read sequentially. Temporary variables are defined for local use only.
| A | amplitude response |
| A min | minimum attenuation |
| a | radius of the inner conductor of a coaxial line |
| a t | line attenuation |
| a 1 | incident S-parameter voltage wave at the network input divided by the square root of the reference impedance |
| a 2 | incident S-parameter voltage wave at the network output divided by the square root of the reference impedance |
| B | magnetic vector field |
| B n,n+1 | susceptance of series coupling capacitors between resonator n and n+1 |
| b | radius to the inside of the outer conductor of coax |
| b 1 | reflected S-parameter voltage wave at the network input divided by the square root of the reference impedance |
| b 2 | incident S-parameter voltage wave at the network input divided by the square root of the reference impedance |
| C t | total normalized node... |
