Total Power in AM (Single-Tone) (P_T = P_c(1 + μ²/2))
jee-mainjee-advancedneet-ug
P_T = P_c(1 + μ²/2)
What each symbol means
| Symbol | What it stands for |
|---|---|
| μ | Modulation index for sinusoidal modulation |
| P_T | Total average power in the AM signal (carrier + sidebands) |
| P_c | Carrier power for the unmodulated carrier (same load impedance) |
When to use this
Sinusoidal AM; resistive load; time-averaged power. Sidebands each carry (μ²/4)P_c on average → total sideband power (μ²/2)P_c.
