Question

If the F_CLk/f0 mode is halved from 100 to 50 then the top of the range of the cut-off frequency of a Low-Pass Filter will be: a doubled b. halved. c unaltered d. same as the clock For a given clocking frequency, the relationship between the frequencies of the Band Pass/stop and the Low/High Pass Filter functions of the switched capacitor is that: a the Band Pass Stop center frequency is higher than the Low/High Pass cut-off frequency. b. the Low/High Pass cut-off frequency is higher than the Band Pass/Stop center frequency C both cut-off and center frequencies are the same. d the Band Pass/Stop Filter center frequency is not adjustable. The rejection of a single Notch Filter is likely to be about: a -3 dB b -20dB c -46 dB d -80dB The harmonic components of a square wave are: a all harmonics of descending amplitude. b even harmonics of equal magnitude c odd harmonics of descending amplitude. d odd harmonics of increasing magnitude. The Q Factor required for a Band Pass Filter to be used to analyze the frequency components of a complex wave is: a less than 1 b 1.3 c about 1.6 d very high.

Explanation / Answer

5.The Q factor required for a band pass filter to be used to analyze the frequency components of a complex wave is very high

3.The rejection of a single notch filter is likely to be about -46 dB
