Teledesign Systems, Inc Confidential Information Page 4
Channel Baud Rate (B) = 2400 bps
Modulation Frequency (M) = B (1/3) = 800 Hz
Peak Deviation (D) = 1500 Hz
Bandwidth Calculation = 2 (D) + 2 (M)
Bandwidth Calculation = 2 (1500) + 2 (800)
Bandwidth Calculation = 3000 + 1600
Bandwidth Calculation = 4600 or 4K60
GMSK with BT = 0.5 20K0F1D:
Channel Baud Rate (B) = 14000 bps
Modulation Frequency (M) = B (1/2) = 7000 Hz
Peak Deviation (D) = 3000 Hz
Bandwidth Calculation = 2 (D) + 2 (M)
Bandwidth Calculation = 2 (3000) + 2 (7000)
Bandwidth Calculation = 6000 + 14000
Bandwidth Calculation = 20000 or 20K0
16K0F1D:
Channel Baud Rate (B) = 10000 bps
Modulation Frequency (M) = B (1/2) = 5000 Hz
Peak Deviation (D) = 3000 Hz
Bandwidth Calculation = 2 (D) + 2 (M)
Bandwidth Calculation = 2 (3000) + 2 (5000)
Bandwidth Calculation = 6000 + 10000
Bandwidth Calculation = 16000 or 16K0
11K2F1D:
Channel Baud Rate (B) = 7200 bps
Modulation Frequency (M) = B (1/2) = 3600 Hz
Peak Deviation (D) = 2000 Hz
Bandwidth Calculation = 2 (D) + 2 (M)
Bandwidth Calculation = 2 (2000) + 2 (3600)
Bandwidth Calculation = 4000 + 7200
Bandwidth Calculation = 11200 or 11K2
