Gated Sinusoid Waveform
The Gated Sinusoid defines a sine wave that is gated on and
off by a trapezoidal waveform. The frequency of the gating trapezoid is
the same as the frequency of the sine wave. One cycle of the waveform is
displayed in the upper graph of the form.
The waveform has zero amplitude at time zero.
Peak Amplitude sets the sine wave
peak amplitude.
Frequency sets the waveform
frequency.
Duty Cycle sets the percentage of
the waveform period that the sine wave is gated off by the trapezoidal
waveform.
Duration sets the length of time
from the end of the rise time to the start of the fall time.
Rise Time sets the time from zero
amplitude to the point at which the trapezoid amplitude equals the sinusoid
amplitude. Rise time is linear. Rise time may not be less than
1/(4*Frequency), i.e. one-fourth of the waveform period.
Fall Time sets the time from when
the trapezoid amplitude equals the sinusoid amplitude to zero amplitude.
Fall time is linear. Fall time may not be less than 1/(4*Frequency), i.e.
one-fourth of the waveform period.
The times at which the trapezoidal rise and fall
transitions begin are determined by Duration, Rise Time, and Fall Time.
