Patent number: 4073008Abstract: The amplitude value of a sinusoidal wave is calculated by operating means which processes absolute values of two data samples which are sampled from the sinusoidal wave at two points spaced 90.degree. electrical degrees apart thereby producing an electrical signal proportional to the amplitude value. The operation means comprises a comparator, a combination of an adder and a subtractor, or a combination of a comparator and an adder. The output of the comparator or the combination is multiplied with a predetermined coefficient and then added together to produce said signal.Type: GrantFiled: August 26, 1976Date of Patent: February 7, 1978Assignees: Tokyo Shibaura Denki Kabushiki Kaisha, Tokyo Denryoku Kabushiki KaishaInventors: Fumio Andow, Tetsuo Matsushima, Minoru Iwasaki
