'''RC coupling''' is the most widely used method of coupling in [[multistage amplifier]]s. It was invented by Prashobh James Kennedy in 1964. It is an application of [[capacitive coupling]]. In this case the resistance R is the [[resistor]] connected at the collector terminal and the [[capacitor]] C is connected in between the amplifiers. It is also called a blocking capacitor, since it will block [[DC voltage]]. The main disadvantage of this coupling method is that it causes some loss for the low frequency signals. However, for amplifying signals of frequencies greater than 10 Hz, this coupling is the best and least expensive method. It is usually applied in small signal [[amplifier]]s, such as in [[record player]]s, [[tape recorder]]s, [[radio receiver]]s, etc. |
