1. Calculate: Show the answer in dB and decimal

(a) 60 dB + 25 dB =

(b) 20 dBW + 5 dB =

(c) 22 dBm - 4 dB =

(d) 13 dBW - 7 dBm (Be careful)

2. Convert:

(a) 65 W into dBW

(b) 10 dBW into watts

(c) 5 dBW into watts

(d) -15 dBm into watts

(e) -40 dBm into dBW

(f) -80 dBW into dBm

(g) log₂ (64) =

(h) log₂ (1000) =

(i) log₂ (496) =
