Question

Give the correct units (dB or dBm):

the loss in a filter ____

The EIRP of a transmitter ____

The output power of a transmitter _____

The signal detected by a receiver _____

The gain of an antenna _____

Answer 1

1)the loss in a filter (dB)

the unit of loss in filter is always measured in dB

it is the ratio of signal level to the test confriguration without filter to the signal level with filter..

2)The EIRP of a transmitter (dBm)

effective/equivalent isotropic radiated power  is the measured radiated power in a single direction always measure in dBm

3) The output power of a transmitter (dBm)

it is define as the actual amount of power(in watts) of radio frequency (RF) energy that a transmitter produces at its output.. it is always measured in dBm

4)The signal detected by a receiver (dB)

always measured in dB

5)The gain of an antenna (dB)

it is the ratio of power produced byy the antenna from a far field source on the antenna's beam axis to power produced by hypothetical lossless isotropic antenna...

it is always measured in dB
