- 4.0 Selection of Output Quantities and Frequency Sweep
- ==================================================
-
- After a circuit has been input, but before calculation beings, you will need to
- select those quantities you wish to observe and the frequencies at which to ob-
- serve them. There are two ways that the program can provide output. printed
- table of up to 50 quantities per frequency, or a displayed plot.
- Only one method can be selected at a time.
-
- Available output quantities are node voltages, branch voltages, branch currents
- branch power and ratio of any two quantities. Node voltage zero is not avail-
- able for output, but is always 0 volts at 0 degrees. A branch voltage is the
- voltage across an element. It is the node voltage at the positive node minus
- the node voltage at the negative node. The positive node for a controlled or
- independent current source, by convention, is the node where the current leaves
- the source (the TO node). The positive node for resistors, inductors and capa-
- citors again by convention, is the node where current enters the element ( the
- FROM node.
