Explanation: Frequency shift is usually accomplished by dividing a VCO with binary data signal. Therefore, the logic 1 state of the binary data signal corresponds to mark frequencies. 7. Find the frequency shift in FSK generator?
A. 230 Hz
B. 250 Hz
C. 180 Hz
D. 200 Hz
Answer:A
Explanation: Frequency shift is usually accomplished by dividing a VCO with binary data signal. Therefore, the logic 1 state of the binary data signal corresponds to mark frequencies. 7. Find the frequency shift in FSK generator?
A. 230 Hz B. 250 Hz C. 180 Hz D. 200 Hz
Explanation: Frequency shift is the difference between FSK signals of 1070 Hz and 1270 Hz frequency, which is 200 Hz. 8. Which filter is chosen to remove the carrier component in the frequency shift keying?
