An NSF Research Experience for Teachers Program

- Introduction to GNU Radio & Signals
This lab is a guided tutorial on GNU Radio including an installation guide. The guided exercises involve development of waveform generation and manipulating graphic user interfaces.

- 1.1. Signals Continued: Sampling
A short exploration of random Signals and Sampling

- 1.1. Signals Continued: Sampling
- First steps with SDR Hardware
This lab involves working with hardware i.e. the SDR dongle. We shall build a simple FM radio

- Introduction to Fourier Analysis
This is an introductory exercise in Fourier Analysis by way of Harmonic Analysis using Fourier Series.

- 3.1. Fourier Series and Fourier Transforms
Let’s find out what all this fourier fuss is all about!

- 3.1. Fourier Series and Fourier Transforms
- Filters
To implement filters. We shall make a an “

*equalizer*” for the demodulated FM audio using the filters. Extract fundamental frequencies from a piano chord. Build a guitar tuner. - Fourier Analysis – Expert Mode!
Revisit Fourier Transform, FT properties, IQ sampling, Optionally, Implement a simple N-point

*Fast Fourier Transform*. Use the gnuradio FFT block and filters from the previous exercise to build a spectrometer. Intruduction to Polyphase filterbanks as an added upgrade to the spectrometer. - A Radio Telescope
- Build an Antenna
- Assemble Low Noise Amplifier
- Inegration of Antenna to SDR dongle to GNU Radio companion.

- Observations
- Making measurements
- Caliberating
- Mapping the neutral hydrogen
- Rotation Curve of the Milky Way
