Figure $19

Question

Figure $19 < 5$
-The curve in Figure 19-5 is from a ________ and its lower cutoff frequency equals ________.
A)two-pole high-pass filter, 1500 Hz 
B)band-reject filter, 450 kHz 
C)band-pass filter, 822 Hz 
D)band-pass filter, 450 Hz

Quizplus · Accepted Answer

The curve in Figure 19-5 shows a band-pass filter with a peak around 450 Hz and -3dB cutoff frequencies at approximately 100 Hz and 800 Hz. Therefore, the answer is D, band-pass filter with a lower cutoff frequency around 100 Hz (the graph is not precise enough to determine an exact value). Choices A and B are incorrect because their frequency cutoffs do not align with the graph, and C is incorrect because the peak frequency is not near 822 Hz.
