Task 4
[Criteria: P7]
Use a computer simulation package such as Yenka or Multisim to build the BJT (e.g.
BC108) amplifier circuit, with an AC input sine wave Vi= 50 mV @ 1 kHz and DC offset
by trying a blocking capacitor C around 1μF, as shown below. Vo must oscillate about
the Ov axis.
(a)
Using the simulator's Oscilloscope or Graph function to display and measure
the gain Av of the amplifier. Clearly show both Vi and Vo on your graph and
calculate the gain from your test results (you may need to show these on
separate graphs or scales). Clearly Indicate the X (time) and Y (voltage)
scales used.
(b) Confirm your measurement by also calculating the gain for the circuit, that is
completely independent from your test results (i.e. do not use your results
from 4a to complete this calculation)
Take a snip image of your computer-based test results clearly showing the simulator's
Oscilloscope or Graph. Save your simulator file as 'U4A1T4' and email a copy along
with your assessment for it to be checked. (or if using Multisim live share/link the file).
