    WHAT IS CIRCUIT SHOP?
    Circuit Shop allows you to design, simulate and learn about
    digital and analog electronic circuits.  Circuit Shop is an
    easy to use graphical CAD tool to allow simple digital and analog
    electronic circuits to be constructed and analyzed.  It includes:
    * Drawing tools to construct simple electronic circuit schematics
      consisting of digital and analog devices such as ICs, logic
      gates, flip-flops, op amps, dependent sources, transistors,
      resistors, batteries, etc.
    * A tutorial which teaches basic digital and analog electronic
      concepts.
    * Digital circuit design and analysis capability using digital
      sources, logic gates, flip-flops, digital displays and ICs.
    * Analog circuit design and simulation capability to perform
      DC analysis, sinusoidal steady state analysis and frequency
      response.  Frequency response includes magnitude, Bode,
      phase, dB and group delay plots.
    * A simple paint toolkit to allow text, lines, ovals and
      rectangles to be added as circuit annotations.
    * A printable version of Circuit Shop's on-line help file can
      be downloaded from the Circuit Shop home page.  The fully
      indexed PDF document consists of a reference manual and a
      basic electronics tutorial.

    TO BECOME FAMILIAR WITH CIRCUIT SHOP FEATURES
    Circuit Shop's help file CIRC.HLP contains an extensive
    electronics tutorial including a number of step-by-step
    demonstrations.  The step-by-step demonstrations can be used
    to learn how to use Circuit Shop's graphical drawing tools and
    circuit analysis features.  The most basic demonstration is in
    the Ohm's Law tutorial, search for help topic Ohm's Law
    Demonstration Circuit in the above help file.
