Skyhawk16,

I'll assign it to you considering you've shown interest. 

As noted, there are questions that require showing calculation steps.

I'll attach the file again for your convenience.

Please respond in MS Word .docx format.

1. Apply 3's rule to estimate what 16 mWs is in dBm. _____ 2. Apply 3's rule to estimate what 0.0625 mWs is in dBm. _____ 3. Apply 10's rule to estimate what 10,000 mWs is in dBm. _____ 4. Apply 10's rule to estimate what 0.0001 mWs is in dBm. _____ 5. Apply 3's rule to estimate what 15 dBm is in mW. _____ 6. Apply 3's rule to estimate what -15 dBm is in mW. _____ 7. Apply 10's rule to estimate what 50 dBm is in mW. _____ 8. Apply 10's rule to estimate what -50 dBm is in mW. _____ Task 2: Estimating power levels using 3's and 10's rules
In cascaded systems with power gain and/or loss along a chain of subsystems, power
levels given in dB forms can be directly added or subtracted to calculate the total power.
For instance, a transmitter with a power of 9 dBm, after a cable and connector loss of 3
dB, ends up with a power of 9 dBm Ë— 3 dB = 6 dBm or 4 mW. Notice that the simple
addition and subtraction here don't apply to powers given in mW.
If one were to subtract 3 dB from 8 mW (i.e., mixed measurement units), 8 mW should
be converted to 9 dBm first. The result is in dBm, which can be converted to mW when
needed.
9. Applying the 3's and 10's rules, what's 0.125 mW Ë— 30 dBm in dBm? _____ 10. Applying the 3's and 10's rules, what's 0.125 mW Ë— 30 dBm in mW? _____ 11. Applying the 3's and 10's rules, what's 0.0625 mW Ë— 40 dBm in dBm? _____ 12. Applying the 3's and 10's rules, what's 0.0625 mW Ë— 40 dBm in mW? _____ 13. Applying the 3's and 10's rules, what's 8 mW + 30 dBm in dBm? _____ 14. Applying the 3's and 10's rules, what's 8 mW + 30 dBm in mW? _____ 15. Applying the 3's and 10's rules, what's 16 mW + 40 dBm in dBm? _____ 16. Applying the 3's and 10's rules, what's 16 mW + 40 dBm in mW? _____
The same idea can be applied to conversions from dBm to mW when a dBm value is
not readily available in the 3's and 10's rules table.
For instance, what is 13 dBm in mW?
First, 13 dBm = 0 dBm + 10 dBm + 3 dBm, where 0 dBm, 10 dBm, and 3 dBm are in the
table. Next, let's apply the following 3's and 10's rules:
a. 0 dBm = 1 mW b. When the dBm value increases by adding 10, the mW value increases by the
factor of 10. c. When the dBm value increases by adding 3, the mW value increases by the
factor of 2.
Finally, we have 13 dBm = 0 dBm + 10 dBm + 3 dBm = 1 mW × 10 × 2 = 20 mW. 17. Applying the 3's and 10's rules, what's 7 dBm in mW (must show steps)?
Answer: 18. Applying the 3's and 10's rules, what's 4 dBm in mW (must show steps)?
Answer: 19. Applying the 3's and 10's rules, what's 9 dBm in mW (must show steps)?
Answer: 20. Applying the 3's and 10's rules, what's -7 dBm in mW (must show steps)?
