Tutorial 6: Useful special devices
1. Digital devices
The digital devices reside in the "digital.lbr"
library. Their main purpose is to model small digital parts of your circuitry
using transient analysis. From the eagle control panel, double click onto
the "count4" schematic symbol to see a (pure digital) application example:
The lower two green textlines define the reset and the clock sources
to stimulate the counter. I have added some voltage to the different measurement
instrument channels to separate the waveforms from one another.
2. Voltage controlled Resistors, Capacitances and Inductances
These are useful if you want to optimize your
circuit. You may use e.g. the voltage controlled capacitance to trim your
filter circuit to resonance in transient analysis.
Another application would be to model real parts like e.g. a potentiometer.
3. Abstract Parts
Adder, Subtractor, Multiplier and other parts
will help you to model parts of your circuitry on a conceptual level before
going the hard way to implement the function with real parts.
