This table provides values for some normalized waveforms:
| Wave type | Waveform | Peak magnitude (normalized) | RMS value | Crest factor | PAPR (dB) |
|---|---|---|---|---|---|
| DC | 1 | 1 | 1 | 0.0 dB | |
| Sine wave | 1 | 3.01 dB | |||
| Full-wave rectified sine | 1 | 3.01 dB | |||
| Half-wave rectified sine | 1 | 6.02 dB | |||
| Triangle wave | 1 | 4.77 dB | |||
| Square wave | 1 | 1 | 1 | 0 dB | |
| PWM-Signal V(t) 0.0V |

| QPSK | 1 | 1 | 1 | 0 dB | |
| 8VSB | 6.5–8.1 dB | ||||
| 64QAM | 1 | 3.7 dB | |||
| -QAM | 1 | 4.8 dB | |||
| WCDMA downlink carrier | 10.6 dB | ||||
| OFDM | ~12 dB | ||||
| GMSK | 1 | 1 | 1 | 0 dB |
Notes: 1. crest factors specified for QPSK, QAM, WCDMA are typical factors needed for reliable communication, not the theoretical crest factors which can be larger.

Famous quotes containing the word examples:
“It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
—G.C. (Georg Christoph)
“No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.”
—André Breton (1896–1966)
“In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
—Michel de Montaigne (1533–1592)
