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.
An RF power amplifier is tuned to a single frequency as low as 18 kHz and as high as the UHF range of frequencies, for the purpose of radio transmission or industrial heating. They use a narrow tuned circuit to provide the valve with a suitably high load impedance and feed a load that is typically 50 or 75 Ohms.
