Question



My question is very simple. I solved everything except part f in Prob#2 as shown in the picture because I didnt understand it.
The old bandwidth value ( before putting the Rload) = 91 Hz, and the new bandwidth value ( after putting the Rload)= 89 Hz . So what is the answer for part f ?
Thanks in advance.

Prob #1 A series RLC band-pass filter with a cuttoff freqencies of lkHz, 13kH. and C = 1 all is to be designed. a) Calculate the values of R and L. c b) Use PSpice to plo11he·'output voltage vo versus f (0

Explanation / Answer

Fold = 91 Hz

Fnew= 98 Hz

Vo/Vi = R1 /(R1 + R2+1/sC)

LOAD R1 increases , deacrese the bandwidth and vice versa
