Performance Task
Code Designation
Objective:
At the end of the exercise, the students should be able to:
▪ Classify the code designations of various radio emissions.
Instruction: Convert the following using various code designations. Identify the types and/or provide details
for each code. (90 points)
Using ITU Code Designations:
1. Amplitude and phase-modulation with two or more channels with quantized or digital information
2. Pulse position modulated with a single channel with a digital signal, telephony
3. Amplitude-modulated, analog with multichannel with machine-coded information
4. Single-sideband suppressed carrier with a single channel consisting of quantized or digital information
for data transmission
5. Single channel phase modulation telegraphy (machine)
6. Frequency modulation single channel analog telephony
7. Unmodulated Pulse Emissions
Using Bandwidth Designations:
8. 65M2
9. 3G90
10. 81k9
11. 2H31
12. 47G5
Using Radio Emission Code Designations:
13. DSB two sidebands, 100% pilot carrier from voice
14. Phase modulation with single sideband, no carrier, telephony
15. Frequency modulation with multiple sidebands with a different message, no carrier
