Module 7C types of Filters

Question 1

There are four basic types of filter. Name them:

Answer 1

Low-pass
high pass
band pass
band reject

Question 2

What allows frequencies below the upper cutoff frequency to pass unattenuated?

Answer 2

A low pass filter

Question 3

A low pass filter is defined by two parameter. What are they?

Answer 3

upper cutoff frequency and the attenuation rate.

Question 4

What are used to remove high frequency energy from a signal?

Answer 4

Low pass filters

Question 5

What allows frequencies above the lower cutoff frequency to pass unattenuated?

Answer 5

high pass filter

Question 6

A high pass filter is defined by two parameters. Name them.

Answer 6

the low cutoff frequency and the attenuated rate

Question 7

What filters are used to remove low frequency energy from a signal

Answer 7

a high pass filter.

Question 8

what filter is a combination of a low pass and a high pass filter connected in series?

Answer 8

band pass filter

Question 9

What filter allows a band of frequencies to pass unattenuated, but attenuates all freuqencies above and below that band.

Answer 9

band pass filter

Question 10

What rejects the sound energy between the upper and lower cutoff frequencies.

Answer 10

band reject filter

Question 11

What is the filter that is opposite of a band-pass filter and is essentially composed of a low pass and a high pass filter that do not overlap with one another?

Answer 11

band reject filter

Question 12

Look at all photos and their notes

Answer 12

:+)

Question 13

What filter has all five filter parameters: upper frequency, lower cut frequency, bandwith,
Center frequency, and attenuation rate(s)?

Answer 13

Band pass filter
