AC Circuit Analysis Lab Graphics and PSpice Simulations

All three lab experiments for the Analysis Lab Course on the site, I added both the lab notes which provides measured results and hand calculations for the individual labs along with the Pspice simulation outputs and in most cases the PSPICE code. You will even see some of the errors I made during these labs such as running a .tran analysis rather then a .AC analysis in Pspice which did effect the output resultant. You can find all these added lab notes at:

RF and Telecommunication Student Experiments

Just Added; no I’m not a late night TV commercial. But seriously, I just added to ClassNotes123.com this evening three more student experiments dealing with radio frequency (RF) and telecom systems. I will be adding the solutions in the coming weeks but for now I have just posted the baseline experiments. They can be found at:

RF Transmit and Receive Link
Measuring Antenna Characteristics using a Network Analyzer
Characterizing a Voltage Controlled Oscillator

FET Capacitance Affects Notes Added

I uploaded several notes pertaining to Field Effect Transistor, Capacitance Affects and Frequency Response to ClassNotes123.com which is part of the Analog and Semiconductor Devices class; an undergraduate course that introduces the topic of nonlinear device. I also added another Satellite Communications homework assignment dealing with look angles. These pages can be located at:

Output Capacitance of a Source Follower Amplifier
Low Frequency Response of a FET Circuit
FET Capacitance Effects
Output Capacitance of a Drain Loaded Amplifier
Satellite Look Angle Problem

I am finishing up two digital logic laboratories which should be online in the next few days. Stay tune for this and more content from ClassNotes123.com
