10+ Senior Assistant Professor Interview Questions and Answers

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

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

Types of representation of numbers include decimal, binary, octal, and hexadecimal.

• Decimal representation uses base 10 and consists of digits 0-9.

• Binary representation uses base 2 and consists of digits 0 and 1.

• Octal representation uses base 8 and consists of digits 0-7.

• Hexadecimal representation uses base 16 and consists of digits 0-9 and A-F.

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.

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

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).
