Transmit Delay, Absolute (f = 1600Hz)
Transmit Delay, Relative to D
f = 500Hz - 600Hz
f = 600Hz - 800Hz
f = 800Hz - 1000Hz
f = 1000Hz - 1600Hz
f = 1600Hz - 2600Hz
f = 2600Hz - 2800Hz
f = 2800Hz - 3000Hz
Receive Delay, Absolute (f = 1600Hz)
Receive Delay, Relative to D
f = 500Hz - 1000Hz
f = 1000Hz - 1600Hz
