Lab 0

Example1

A simple example to understand the use of boolean operators. In this example, two idependent random source are used that generates 0 and 1. The output of the sources are used as inputs in an XOR operator.

Example2

Example2 focuses on adding tags in curves.

Example3

Example3 combines two cosine waveforms of different frequencies and plots their frequency and time responses.

Example4

Example4 plots the histogram of a uniform random variable.

Example5

Example5 demonstrates how to add a delay to a signal.

Example6

Example6 demonstrates the use and implementation of bandpass filter (BPF) in gnuradio.

Example7

Example7 demonstrates the implementation and use of the downsampler in gnuradio.

Example8

Example8 demonstrates the implementation and use of the high pass filter (HPF) in gnuradio.

Example9

Example9 demonstrates the implementation and use of the low pass filter (LPF) in gnuradio.

Example10

Example10 demonstrates the use of the "Message Debug" operator in gnuradio.

Example11

Example11 demonstrates the use of the "selector" operator in gnuradio.

Example12

Example12 demonstrates the implementation of colored noise in gnuradio.

Example13

Example13 demonstrates the implementation of a down-converter in gnuradio.

Example14

Example14 demonstrates the use of automatic gain control (AGC) in gnuradio.

Example15

Example15 demonstrates the use of the polyphase synthesizer in gnuradio.

Lab1

Example4

Example4 simulates an AWGN channel.

Example5

Example5 demonstrates the use and functionalities of the Interpolating FIR filter in gnuradio.

Example6

Example6 demonstrates the use of the low pass filter (LPF) in gnuradio.

Example7

Example7 demonstrates how the choise of sampling frequency can influence the quality of the received signal in gnuradio.

Example8

Example8 demonstrates the functionalities of the rational resampler in gnuradio.

Example9

Example9 demonstrates how to measure the power of a received signal in gnuradio.

Example10

Example10 demonstrates how to measure the average power of a received signal in gnuradio.
