Equalisation Quiz

Which type of filter would you use to attenuate frequencies below 200 Hz?

• Low-pass filter

• High-pass filter

• Band-pass filter

• Shelving filter

What does a low-pass filter do?

• Amplifies frequencies below a certain cutoff frequency

• Attenuates frequencies above a certain cutoff frequency

• Attenuates frequencies below a certain cutoff frequency

• Amplifies frequencies above a certain cutoff frequency

What does a high-pass filter do?

• Amplifies frequencies below a cutoff frequency

• Attenuates frequencies above a certain cutoff frequency

• Attenuates frequencies below a certain cutoff frequency

• Amplifies frequencies above a certain cutoff frequency

Which filter would most effectively remove the hum at 50 Hz from an audio signal?

• Low-pass filter with a cutoff at 60 Hz

• High-pass filter with a cutoff at 60 Hz

• Parametric EQ cut at 50 Hz

• Parametric EQ boost at 50 Hz

What unit is the slope of a filter's attenuation usually specified in?

• Hertz (Hz)

• Decibels per octave (dB/octave)

• Milliseconds (ms)

• Watts (W)

A high-pass filter is sometimes referred to as:

• Lo-cut filter

• Treble boost filter

• Bass boost filter

• Treble cut filter

Which statement is true regarding a low-pass filter?

• It allows low frequencies to pass through while attenuating high frequencies.

• It allows high frequencies to pass through while attenuating low frequencies.

• It boosts both high and low frequencies while attenuating mid frequencies.

• It attenuates both high and low frequencies equally.

In audio equalisation, what is the main difference between a shelving filter and a peaking filter?

• A shelving filter adjusts the amplitude of all frequencies equally, while a peaking filter adjusts only a specific range.

• A shelving filter adjusts the amplitude of frequencies above or below a certain point, while a peaking filter boosts or cuts a specific frequency range without affecting the others.

• A shelving filter can only boost frequencies, while a peaking filter can both boost and cut frequencies.

• There is no difference; they are two terms for the same type of filter.

What is the effect of increasing the Q factor in a high-pass filter?

• It broadens the range of frequencies that are attenuated.

• It reduces the filter's slope.

• It narrows the range of frequencies that are attenuated.

• It decreases the overall volume of the signal.

To make a vocal sound clearer, would you ...?

• Parametric boost +3 dB at 5000 Hz with a medium bandwidth

• Parametric cut -3 dB at 5000 Hz with a narrow bandwidth

• High-pass filter at 5000 Hz with an 18 dB/octave slope

• Low-pass filter at 5000 Hz with an 18 dB/octave slope
