Certificates of deposit, or CDs, are fixed income investments that generally pay a set rate of interest over a fixed time period.
When referenced to the local common or ground, a common-mode signal appears on both lines of a two-wire cable, in-phase and with equal amplitudes. Technically, a common-mode voltage is one-half the vector sum of the voltages from each conductor of a balanced circuit to local ground or common.
VCC stands for voltage at the common collector.. The letter V on a circuit stands for the supply voltage. The letters CC indicate that the supply voltage is positive or negative. If the charge is positive, its circuit is a Negative-Positive-Negative circuit, and if negative, it is a Positive-Negative-Positive circuit.
