Frequency Shift Keying Flashcards
What is the difference between the highest frequency level and the lowest frequency level?
Excursion
What is the difference between two adjacent frequency levels?
Shift
What is the shift equal in FSK?
Excursion
What is the formula to work out the SMI?
Fd/fm or shift/bauds
What is the formula for working out the minimum bandwidth?
2(fd+fm) or shift+bauds
If baud speed is 50 and SMI is 20, what is the shift?
1000, baud x SMI
What is the drop between the major lobe and minor lobes in an MSK signal?
23.7dB
In MSK signals, what is the width of the minor lobe equal to?
Shift
In MSK signal, what is equal to 1.5x keying rate?
Width of major lobe
In MSK signal, what special relationship does baud speed have with shift?
Baud=shiftx2
