Look up the manual of ELVIS II, which can be downloaded here, find out how to generate AM and FM waveforms using the AM and FM inputs. Specifically, pay attention to the AM and FM inputs to the FGEN, and the use of ARB, AO1 and AO2. Write down the equations used by ELVIS II to determine amplitude at any given time t for AM. You will need to use this equation and compare calculated and measured amplitudes versus t in your lab report.
Write down the equations used by ELVIS II to determine frequency at any given time t for FM.
Print out screen shots of the manual pages where you found the equations.
The IR LED and photo transistor as shown in the breadboard photo of the IR link are hard to see, because the packages are clear or transparent, unlike the 2N3904 transistor we used earlier. Can you think of any reasons for such difference in packages?
