Dan Boschen

Quick Start on Control Loops with Python
Available in 1 day, 2 hours and 18 minutesControl loops are ubiquitous in various applications where we wish to maintain or stabilize process variables to a desired set point or value. The speaker, Dan Boschen, brings a wealth of experience in the mixed signal (digital or analog) practical control loop design of microwave synthesizers, modems and radio transceivers, and, most recently, atomic clocks.
In this live workshop, Dan will first provide an overview of control loop theory sufficient for the implementation of a Phase-Lock-Loop (PLL). Topics covered will include:
- Transfer Functions
- Loop Order and Tracking
- Stability
- Bode and Nyquist Plots
- Noise Transfer Functions
PLL implementations in both the analog and all-digital domain will be detailed for practical implementation. The modeling and simulation of control loops will be demonstrated with use of the free Python programming language.
This is a great opportunity for anyone wishing to get a quick jump start on practical control loop implementations in the both the digital and analog domains, and to see what Python can offer for use in the simulation and modeling of control loops.
Demystifying the Hilbert Transform
Status: Available NowWorkshop 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.
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.
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.
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.
