Phase shifting of waveforms |
摘要 |
A signal having the form cos ( OMEGA t+ phi ) where OMEGA is the frequency of the signal and phi is a phase angle which may be zero is phase shifted to improve the results of the summation of such a signal with other signals having the same form but different phase angles.
