22.
Consider 49 cascaded amplifiers having individual rise time as 2 n sec. 3 n sec. ... 50 n sec. The input waveform rise time is 1 n sec. Then the output signal rise time is given time by (Assume output signal rise time is measured within 10 percent range of the final output signal.)
Answer: Option
Explanation:
Output rise time (tr) 
1.1ti02 + t12 + ... + t492,
where t, t2 ... t49 are the individual rise time.
tr 1.1 (1 ns)2 + (2 ns)2 + (50 ns)2
1.1
0.228 msec.
