Q1. What are the 2 types of convolution with discrete time sequences?

Ans.

The two types of convolution with discrete time sequences are linear convolution and circular convolution.

  • Linear convolution involves summing the products of corresponding elements of two sequences over all possible values.

  • Circular convolution involves summing the products of corresponding elements of two sequences after wrapping around the end of the sequences.

  • Example: Linear convolution - [1, 2, 3] * [4, 5, 6] = [4, 13, 28, 27, 18]

  • Example: Circular convolution - [1, 2, 3] o...read more

Q2. What are the steps involved in Analog-to-Digital(A/D) conversion?

Ans.

Analog-to-Digital conversion involves sampling, quantization, and encoding of analog signals into digital form.

  • Sampling: capturing the analog signal at discrete time intervals

  • Quantization: converting the sampled values into discrete levels

  • Encoding: representing the quantized values in binary form

  • Example: In audio recording, the continuous sound wave is sampled at regular intervals, quantized into specific levels, and encoded into digital data

  • Ease of implementation: Digital signal processing can be implemented using software on a computer or dedi...read more

Q6. What are the applns. of DSP in speech?

Ans.

DSP in speech is used for speech recognition, noise cancellation, audio compression, and synthesis.

  • Speech recognition: DSP algorithms are used to analyze and recognize spoken words.

  • Noise cancellation: DSP techniques can remove background noise from speech signals.

  • Audio compression: DSP is used to compress audio data for efficient storage and transmission.

  • Speech synthesis: DSP algorithms can generate human-like speech from text input.

Q8. What are the types of FFT?

Ans.

Types of FFT include Cooley-Tukey, Radix-2, Radix-4, Split-Radix, Prime Factor, and Bluestein.

  • Cooley-Tukey: most common FFT algorithm, divides input into smaller DFTs

  • Radix-2: divides input into smaller DFTs of size 2

  • Radix-4: divides input into smaller DFTs of size 4

  • Split-Radix: combines Radix-2 and Radix-4 algorithms for efficiency

  • Prime Factor: decomposes DFT into smaller prime factor DFTs

  • Bluestein: used for arbitrary length input sequences

Q9. Mention the types of digital filters?

Ans.

Types of digital filters include FIR filters, IIR filters, and adaptive filters.

  • FIR filters: Finite Impulse Response filters have a finite duration impulse response.

  • IIR filters: Infinite Impulse Response filters have a feedback loop in their design.

  • Adaptive filters: These filters adjust their parameters based on input signals to optimize performance.

  • Examples: Butterworth filter (IIR), Chebyshev filter (IIR), and Kalman filter (adaptive).
