555555555530. In a multistage amplifier, the overall frequency response is determined by the (a) frequency response of each stage depending on the relationships of the critical frequencies. (b) frequency response of the first amplifier. (c) frequency response of the last amplifier. (d) lower critical frequency of the first amplifier and the upper critical frequency of the final amplifier.
555555555529. For low-frequency response, all RC circuits in an amplifier may not have the same critical frequency. Which RC response will determine the critical frequency of the amplifier? (a) the lowest frequency (b) the center frequency (c) the highest frequency (d) the bypass frequency
