Digital Signal Processing Certification

In this article, we will explore what a Digital Signal Processing certification is, why it is important, and how you can go about getting certified in Digital Signal Processing by Sanfoundry for free.

What is a Digital Signal Processing certification?
A DSP certification is a professional credential demonstrating an individual’s proficiency in Digital Signal Processing. The certified professional has in-depth knowledge of topics such as:

  • analysis and application of appropriate frequency transformations for any class of signal.
  • analysis and design of filters for a given signal processing application.
  • computation of the errors encountered in digital signal processing systems.
  • design of applications that involve signal and image processing by adopting appropriate transformation and filtering techniques.
  • addition of possible extensions to digital filters for a given application.
  • design of a signal processing system.
  • design of analog and digital filters.
  • knowledge of fourier transform and its applications.
  • design of infinite and finite impulse response filters for filtering undesired signals.
  • understanding of signal processing concepts in systems having more than one sampling frequency.
  • design of applications that involve signal and image processing.
  • knowledge of advanced concepts of signal processing (multirate and adaptive filtering) and architecture of DSP processor.
  • computation of DFT by FFT algorithms.
  • development of transformation from analog system to digital system and design and implementation of IIR and FIR filters.

Which certification is best to work in the field of Digital Signal Processing?
The free Digital Signal Processing certification offered by Sanfoundry is good for those looking to work in the field of Digital Signal Processing. Other certification include the Certified Digital Signal Processing Professional (CDSPP) certification offered by the International Council on Systems Engineering (INCOSE), Certified Digital Signal Processing Professional (CDSP) offered by IEEE.

What type of job can I get with a Digital Signal Processing certification?
Digital Signal Processing (DSP) is the science of manipulating, analyzing, and transforming digital signals. With a certification in this field, you can find jobs in research and development or engineering. Some of the most common types of jobs that require a DSP certification include research engineer, system engineer, software developer, data analyst, machine learning specialist, audio engineering, video compression, image processing or even robotics and automation.

Sanfoundry DSP Certification

Sanfoundry offers online certification in Digital Signal Processing for free. The certification exam is divided into two parts: Qualifier Test and Certification Test.

First step is to take the "Qualifier Test". If you have scored at least a B grade in the "Qualifier Test", then only you would be eligible to take part in the online "Certification Test". If you have scored an A* (Genius) or A (Excellent) grade in the certification test, then you will be awarded a “Certificate of Merit” in DSP from Sanfoundry.

DSP Certification Exam Overview:

Here are the details and format of the Certification Exam:

  • Format: Online & Multiple Choice
  • Prerequisite: Yes (Qualifier Test)
  • Total Questions: 50
  • Total Time: 1 hour
  • Negative Marking: Yes
  • Fee: Free
Marking Scheme:
In the online certification test, you will be given 2 points for every correct answer. There will also be negative marking of -1 for every wrong answer. So, you have to be more careful in your test. If needed, you should skip to the next question and come back to that question later so that you can manage the time more effectively during the test.

Based on your score, you would be given one of the following Grades:

Grade A* – Genius (You scored 100%)
Grade A – Excellent (Your score is in the range of 80% to 99%)
Grade B – Good (Your score is in the range of 60% to 80%)
Grade C – Average (Your score is in the range of 40% to 60%)
Grade D – Poor (Your score is in the range of 0% to 40%)
