Synonym for Sine Wave Half Cycle
As is often the case, it depends on context. If the entire waveform is present, but you you want to point out a particular half-cycle, you should say &quot;positive half cycle&quot; or negative half-cycle. If you have a zero-crossing switch that lets through a half cycle out of every 5 cycles then you have a series of &quot;sinusoidal pulses&quot; or a series of positive or negative &quot;sinusoidal pulses.&quot; You might shorten that to &quot;sine pulse.&quot;
