这是一篇来自美国的关于实时数字信号处理的编程代写

 

This course is an introduction to the real-time implementation of digital signal processing (DSP) algorithms, with an emphasis on audio signal processing and audio effffects.

The course will use Matlab and Python programming. Some Matlab experience is expected. No experience in Python required; the course will introduce Python as needed. This course can be taken independently of ECE 6113 and ECE 7133 (DSP I and DSP II).

Topics include: Audio input-output and buffffering. Filtering (recursive and non-recursive fifilters, structures).

Fast Fourier transform and windowed spectral analysis. Digital audio effffects (delay line, amplitude modulation,reverberation, distortion, short-time Fourier transform). Students will learn to implement these algorithms for real-time audio processing in software.

Prerequisites

Discrete-Time Signal and Systems (undergraduate level is suffiffifficient) (ECE 3054 or ECE 6113 or equivalent) You should know: discrete-time convolution, Z-transform, transfer function, frequency response, difffference equations, pole-zero diagrams, and the discrete-time Fourier transform.

Learning objectives

1. The implementation and design of algorithms for signal processing with an emphasis on audio processing.
2. Software-based real-time programming of signal processing functions (real-time fifiltering, time-varying fifiltering, spectral analysis, audio effffects).

Learning outcomes

1. Students will be able to use Matlab and Python to perform signal processing functions (fifiltering, spectral analysis, fifilter design).

2. Students will understand constraints and parameters associated with real-time signal processing (sampling rate, latency, buffffering, bits per sample).

3. Students will be able to write programs to perform audio effffects (reverberation, delay line effffects, amplitude modulation, distortion).

NYU School of Engineering Policies and Procedures on Academic Misconduct

Introduction: The School of Engineering encourages academic excellence in an environment that promotes honesty,integrity, and fairness, and students at the School of Engineering are expected to exhibit those qualities in their academic work. It is through the process of submitting their own work and receiving honest feedback on that work that students may progress academically. Any act of academic dishonesty is seen as an attack upon the School and will not be tolerated. Furthermore, those who breach the School’s rules on academic integrity will be sanctioned under this Policy. Students are responsible for familiarizing themselves with the School’s Policy on Academic Misconduct.

Defifinition: Academic dishonesty may include misrepresentation, deception, dishonesty, or any act of falsifification committed by a student to inflfluence a grade or other academic evaluation. Academic dishonesty also includes intentionally damaging the academic work of others or assisting other students in acts of dishonesty. Common examples of academically dishonest behavior include, but are not limited to, the following:

1. Cheating: intentionally using or attempting to use unauthorized notes, books, electronic media, or electronic communications in an exam; talking with fellow students or looking at another person’s work during an exam; submitting work prepared in advance for an in-class examination; having someone take an exam fo you or taking an exam for someone else; violating other rules governing the administration of examinations.

2. Fabrication: including but not limited to, falsifying experimental data and/or citations.
3. Plagiarism: intentionally or knowingly representing the words or ideas of another as one’s own in any academic exercise; failure to attribute direct quotations, paraphrases, or borrowed facts or information.

4. Unauthorized collaboration: working together on work that was meant to be done individually.
5. Duplicating work: presenting for grading the same work for more than one project or in more than one class, unless express and prior permission has been received from the course instructor(s) or research adviser involved.

6. Forgery: altering any academic document, including, but not limited to, academic records, admissions materials, or medical excuses.
