DATU PUTI

Which of the following is NOT a classification of signals?

• Continuous-time

• Discrete-time

• Dynamic-time

• Analog

What defines a periodic signal?

• It has a repeating pattern over a specific interval

• It has a continuous spectrum

• It does not repeat its pattern

• It has no fundamental frequency

What is the Nyquist rate?

• Half the sampling frequency

•   Twice the highest frequency component in the signal

•   Equal to the highest frequency component in the signal

• Equal to the sampling frequency

Aliasing in signal processing occurs when:

•   The sampling frequency is too low

• The sampling frequency is too high

•   The signal is continuous

•   The signal is periodic

What differentiates a Finite Impulse Response (FIR) filter from an Infinite Impulse Response (IIR) filter?

•   FIR filters use feedback

• IIR filters have a finite number of coefficients

• IIR filters have an infinite impulse response

• FIR filters have recursive difference equations

Which type of filter exhibits linear phase characteristics?

• IIR Filter

•   FIR Filter

• Both FIR and IIR

• Neither FIR and IIR

Which of the following is a characteristic of Finite Impulse Response (FIR) filters?

• They exhibit recursive behavior

•   They have an infinite impulse response

• They can have feedback loops

• They have a finite duration impulse response

The z-transform is used to:

• Convert time-domain signals to frequency-domain signals

• Convert frequency-domain signals to time-domain signals

• Evaluate poles and zeros of a system

• Perform convolution operations

  Pole-zero-gain filters are characterized by:

•   Number of poles and gain

•   Number of zeros and gain

•   Number of poles, zeros, and gain

•   Only the gain

In signal processing, Fourier transforms are primarily used for:

•   Time-frequency analysis

•   Evaluating system poles and zeros

•   Modifying phase response of a filter

•   Converting frequency-domain signals to time-domain signals
