Types of modulation – classification
Old and new designations of emissions Classification (based on old method)
Example: = SSB Telephony, suppressed carrier, bandwidth 2700 Hz
1. Three digits plus H.K. M or G (Hz, kHz MHz or GHz) occupying decimal point place - necessary bandwidth.
2. Three characters (per table above) indicating type of emission.
3. Two optional characters giving further information on type of transmission.
= SSB Telephony, suppressed carrier, bandwidth 2700 Hz
