For the circuit in figure 8, would you characterize this transistor amplifier as being inverting or non-inverting to outputs 2+ and 2- with the base terminal of transistor Q1 being considered the input?
By analyzing the plot for the circuit in figure 8, we can notice that the there is a 180-degree phase shift between the input trace and the output trace, therefore we can conclude that the amplifier has an inverting behavior.
For the same circuit, describe what happens to each of the output voltages (2+ and 2-) as the input voltage (W1) increases, decreases.
The easiest way to analyze the output/input relationship with respect tot the amplitude is to simulate the circuit using LTspice software, or using the ADALM2000/Scopy setup. By increasing the input voltage amplitude, we will notice an increase in the amplitude of the output voltage.By decreasing the input voltage amplitude, we will notice a decrease in the amplitude of the output voltage. Therefore, we can conclude that the input/output voltage out the circuit are directly proportional.
