Engineering at Dordt College

On Tuesdays we have our EGR 323 Electronics II lab. Today we built class B and class C amplifiers. These are more efficient that class A amplifiers although they can also produce more distortion. The students were able to use an oscillosocpe to see the crossover distortion typical of class B amplifiers. They also were able to get the class C amplifiers working at fundamental as well as harmonic frequencies.
