5 days ago In this experiment, using the circuit of Figure 2, the transistors operate in pure class B mode. That is, they are never conducted at the same time. This saves energy and decreases heat dissipation but lends itself to crossover distortion. The solution taken in this circuit is to use an op amp with negative feedback to quickly drive the transistors...
