Chapter 7, Problem 7.127(choose chapter or problem)
A designer, having examined the situation described in 7.125 and estimating the available gain to be approximately 36.3 V/V, wants to explore the possibility of improvement by reducing the loading of the source by the amplifier input. As an experiment, the designer varies the resistance levels by a factor of approximately 3: R1 to 82 k, R2 to 47 k, RE to 7.2 k, and RC to 12 k (standard values of 5%-tolerance resistors). With VCC = 15 V, Rsig = 2 k, RL = 2 k, and =100, what does the gain become? Comment. D 7.1
