The purpose of this experiment is to use Commsim to perform some calculations for us relating to wave propagation.


  1. This Commsim circuit performs the calculations
  2. Start Commsim
  3. Simulate the circuit. You should see the following results:
  4. Use a similar approach to solve for the radio horizon (miles) for the following two antennas:
Antenna Height (feet)
A 50
B 1200


While reviewing your data and results, provide detailed answers to each of the following:

  1. How did you discover the way to perform square-root?
  2. What mathematical functions are missing from Commsim? Can the missing ones be synthesized from existing ones?
