Sine Wave Inverters

Famous quotes containing the words sine and/or wave:

    Faultless honesty is a sine qua non of business life. Not alone the honesty according to the moral code and the Bible. When I speak of honesty I refer to the small, hidden, evasive meannesses of our natures. I speak of the honesty of ourselves to ourselves.
    Alice Foote MacDougall (1867–1945)

    Great Powers of falling wave and wind and windy fire,
    With your harmonious choir
    Encircle her I love and sing her into peace,
    That my old care may cease....
    William Butler Yeats (1865–1939)
