What are some projects in signal processing which could be done only with a preliminary level of signal processing knowledge and resources?

When planning to conduct a specific signal processing project, it is important to consider various aspects like the availability of openly accessible datasets, free software tools such as MATLAB or Python, and the need for fundamental programming expertise. Relevant to signal processing, we suggest a few project plans that are examined as more appropriate as well as interesting:

1. Basic Audio Equalizer

• Goal: To adapt the treble, bass, and mid frequencies of an audio data, model a basic audio equalizer.
• Tools: Employ Python along with suitable libraries such as scipy and numpy.
• Procedure:
  • Utilizing scipy.io.wavfile, read audio data.
  • To separate various frequency bands, implement band-pass filters.
  • In every band, adapt the gain. Then, integrate them appropriately.
  • Compare the altered audio to the actual one after saving it.

2. Simple ECG Signal Analysis

• Goal: Identify any abnormalities such as arrhythmia and detect heart rate by examining ECG data.
• Tools: For plotting, use Python along with matplotlib or MATLAB.
• Procedure:
  • First, load the appropriate ECG dataset, such as from PhysioNet.
  • To eliminate high-frequency noise, implement a low-pass filter.
  • In order to evaluate the heart rate, identify R-peaks.
  • Through the utilization of plots, visualize the outcomes clearly.

3. Image Noise Reduction

• Goal: In images, minimize the noise by applying a basic method like median filter.
• Tools: Use Python with libraries like PIL or OpenCV.
• Procedure:
  • Initially, load a noisy image data.
  • To eliminate salt-and-pepper noise, employ a median filter that is considered as highly efficient.
  • For evaluating the enhancement, compare the images before and after removing the noise.

4. Voice Activity Detection (VAD)

• Goal: In an audio recording, identify when the speech of someone is depicted.
• Tools: For audio processing, utilize Python with Librosa.
• Procedure:
  • The initial process is to load the relevant audio data.
  • By considering short time intervals, retrieve energy or volume.
  • On the basis of energy levels, determine when speech is depicted by setting a threshold.
  • Examine the parts where the voice is identified and output those particular parts of audio.

5. FFT Spectrum Analyzer

• Goal: The frequency spectrum of an audio signal must be examined by developing a tool.
• Tools: It is beneficial to use Python or MATLAB.
• Procedure:
  • Load the targeted audio data.
  • To obtain the frequency spectrum, apply the Fast Fourier Transform (FTT).
  • The audio’s frequency aspects have to be visualized by plotting the spectrum.

6. Biorhythm Tracker

• Goal: According to a person’s date of birth, assess and plot the intellectual, emotional, and physical biorhythms.
• Tools: Utilize any programming language that can perform plotting and fundamental arithmetic operations.
• Procedure:
  • From the person’s birth, count the number of days.
  • To assess the cycles like Intellectual (33 days), Emotional (28 days), Physical (23 days), employ the sine function.
  • For a specific time period, visualize the biorhythms of a person by plotting these cycles.

7. Traffic Light Detection in Images

• Goal: By considering static images, identify and categorize traffic lights.
• Tools: Make use of Python with libraries like OpenCV.
• Procedure:
  • At the beginning, load the street images which specifically include traffic lights.
  • To identify yellow, green, and red lights, utilize color segmentation techniques.
  • For assuring the appearance of traffic lights, implement shape analysis.
  • Then, the class of the traffic light such as red, yellow, or green has to be categorized.
