Find the db strength of the signal

Reference no: EM1380124

Question1. A signal starts at x point. As it travels to y point it loses eight db. At point y the signal is boosted by ten db. As the signal travels to point z it loses 7 db. What is the db strength of the signal at point z?

Question2. What is the decibel loss of a signal that starts at point A with a strength of 2000 watts and ends at point B with a strength of 400 watts?

Question3. If a telephone line can carry a signal with a baud rate of 6000 and we want to transmit data at 33600 bps, how many different signal levels will be necessary? Is this how 33600 bps modem operates?
