Three Stage Amplifier Baseline (No Fault) Circuit Animation.

The Amplifier below is designed for a voltage gain of 3000 to 4000 over a frequency range of 1kHz to a 100 kHz.  The circuit is tested below with a 1mV signal at 100 Hz, 1 kHz, 10kHz, 100 kHz, 1Mhz.   The output voltage must be between 3 and 4 volts AC at the 1k, 10k, and 100k frequencies and less than a 1 volt AC for frequencies of 100 Hz and 1 MHz. Observe Baseline operation recorded below (GIF animation) and than troubleshoot circuit faults 1 - 4 below by identifying failed components.  Only a single failure is inserted into a circuit at a time, but you may not always be able to fault isolate to a single component.  

In setup below Rload , Ammeters, Vcc source and 1mV variable frequency source are part of test bench all other parts belong to Unit Under Test (UUT).

Changing Data forces student to collect data one or two test point at a time.  This is tedious, but not as difficult as collecting test point data is in the real world.  If you wish to download free stop action animations, Click Here!
