These proteins are also part of the immune system (immunoglobulins), help blood to clot (clotting factors), maintain pH balance, and are enzymes involved in chemical reactions throughout the body. Electrolytes are another large category of substances dissolved in plasma. They include:
An ideal op amp has infinite gain (), infinite input resistance ( ), and zero output resistance (). You should use these two assumptions to analyze the op amp circuits covered in the assignments below.
A class 'AB' amplifier is a class 'B' amplifier which has a small amount of 'bias' current flowing through the output transistors at all times. This eliminates virtually all of the crossover distortion that's possible with class 'B' amplifiers.
