Understanding the function of a communication channel
Coding data for transmission via a communication channel
Scanning a signal sequence
Processing a text string, functions
Encryption and decryption of data for protecting the transmission against unauthorised access
Topic
Coding data for communication, synchronised transmitter/recipient, Morse code, encryption (Caesar cipher, Vigenère cipher).
Time required
Students will be able to build the Morse button in just a few minutes.
Depending on their previous experience in programming, students will need 90-180 minutes to develop the programs to solve the programming tasks.
The experimental tasks will require (depending on student grade) another 180-270 minutes. The Morse receiver should be tested in groups using two TXTs.
Students should have been introduced previously to Morse code, the Caesar and Vigenère ciphers (see accompanying materials).
