A non-band-limited pulse oscillator. outputs a high value of one
|
|
|
|
|
and a low value of zero. Note that the iphase argument was not
|
|
|
|
|
present in SC2.
|
|
|
|
|
|
|
|
|
|
freq - frequency in Hertz
|
|
|
|
|
iphase - initial phase offset in cycles ( 0..1 )
|
|
|
|
|
width - pulse width duty cycle from zero to one.
