Question 2: What is the challenge of implementing a filter with a high dynamic range in an algorithm?

Which action should you take?

Choose only one option

It reduces the filter's phase response

It requires more memory for the filter coefficients

It increases the computational complexity

It decreases the precision of signal processing

Question 3: When using a low-pass filter in a signal processing system, what is the main effect on the signal?

Which action should you take?

Choose only one option

It allows high-frequency components to pass while attenuating low-frequency noise

It attenuates low-frequency components

It removes high-frequency components from the signal

It amplifies high-frequency noise

Question 4: What is the purpose of decimation in signal processing?

Which action should you take?

Choose only one option

Equalize frequency response

Reduce the sampling rate of a signal

Amplify low-frequency components

Enhance phase resolution

Question 5: In the context of data filtering, what is the effect of increasing the order of a Butterworth filter?

Which action should you take?

Choose only one option

It sharpens the cutoff frequency response but introduces more phase distortion

It results in a more gradual frequency response and reduced attenuation

It increases the computational complexity without enhancing performance

It improves the phase response but increases noise

Question 6: How does the use of a finite impulse response (FIR) filter in audio processing differ from an infinite impulse response (IIR) filter?

Which action should you take?

Choose only one option

IIR filters have no phase distortion

FIR filters are computationally more efficient than IIR filters

FIR filters cannot handle high-frequency signals effectively

FIR filters can be designed to have linear phase response
