Calculating the rise time of a pulse and finding what is caused to the charge carrier transmit time when the pulse is amplified.

1. When a pulse is amplified in a linear amplifier, the charge carrier transmit time can cause
A) Loss of the d-c reference levels
B) Rise time distortion
C) Waveform tilts
D) Propagation delay

2. It requires five time divisions for a pulse to go from 10 percent to 90 percent of full amplitude. The sweep of the scope is calibrated so that 10 msec are represented by 20 divisions. What is the rise time of the pulse?
A) 0.25 msec (microseconds)
B) 2.5 msec (microseconds)
C) 10 msec (microseconds)
D) 15 msec (microseconds)
