Dan Boschen

Dan Boschen has a MS in Communications and Signal Processing from Northeastern University, with over 25 years of experience in system and hardware design for radio transceivers and modems. He has held various positions at Signal Technologies, MITRE, Airvana and Hittite Microwave designing and developing transceiver hardware from baseband to antenna for wireless communications systems and has taught courses on DSP to international audiences for over 15 years. Dan is a contributor to Signal Processing Stack Exchange https://dsp.stackexchange.com/, and is currently at Microchip (formerly Microsemi and Symmetricom) leading design efforts for advanced frequency and time solutions.

Demystifying the Hilbert Transform

Available in 18 hours and 6 minutes

Workshop Description

In this workshop, Dan will introduce the Hilbert Transform and the Analytic Signal, and the various uses for them. Dan will review the fundamental points in understanding the Hilbert Transform intuitively and then he will show practical implementations and applications both in the analog and digital signal processing domains. Key limitations and gotchas will be presented that every designer should be aware of. Dan will demonstrate creative implementations using Python, and provide similar scripts compatible with MATLAB. Attendees will gain a more intuitive insight of key signal processing concepts using complex signals that are applicable to a wide range of applications.

Workshop Instructions

Thank you for your interest in the Demystifying the Hilbert Transform workshop! Below are the installation instructions for Python in case you want to follow along hands-on with the examples given or run the examples later.

Option 1: Easy path to Python: Install the Anaconda Individual Edition which will have all the tools we will be using: https://www.anaconda.com/products/individual

Option 2: Alternative manual path to Python: As a minimum install we will be using Python 3, Numpy, Matplotlib, and Scipy:

     Install python: https://www.python.org/downloads/

     From command window type: 

         pip install ipython 

         pip install numpy

         pip install matplotlib

         pip install scipy

         (if you encounter any difficulty with installing the packages, see this page: https://packaging.python.org/tutorials/installing-packages/)

Note: We will not be debugging any installation issues in the Workshop, and a Python installation is not necessary to follow along with the workshop presentation. Having a Python installation running with the above libraries is convenient if you want to follow along hands-on, as Dan will be demonstrating the material using Python. A Jupyter Notebook of the material presented will also be distributed here after the workshop for future reference, along with similar scripts that work in Matlab or Octave. If you would like further basics on running the Notebook, please see this link:

Notebook: Fast Track FIR Filter Workshop.ipynb


Finite Impulse Response (FIR) filters are the more popular of the two main types of digital filter implementations used in DSP applications. In this workshop, we will go through best practice approaches for optimized FIR filter design and implementation using the free and open-source Python programming language. This will include the common techniques for going from filter requirements to practical implementation and demonstrate both creating FIR filter designs as well as evaluating filter frequency responses using the Python language and its signal processing library.

This workshop will include:

  • Complete setup to get Python up and running for signal processing applications.
  • Summary of the high-level approaches to FIR filter design – which are best and why?
  • Fast track to using the signal processing library in Python for creating FIR designs.
  • The complete design flow for FIR filters from specification through verification.
  • Using Python for filter evaluation, including plotting magnitude and phase responses.
