PURPOSE:To obtain an optional phase regulating range by exercising phase control over the signal obtained by dividing an input signal and then multiplying said signal. CONSTITUTION:The input signal is supplied to a terminal 130 and then divided into two parts, for example, by a frequency divider 131. These divided signals are supplied to a phase regulator 132. This regulator 132 consists of a capacitor 121, an inductance 122 and a resistance 123 and can continuously regulate the phase between 180 deg. and 0 deg.. Thus the regulator 132 controls the phase of the 2- divided signals. These regulated signals are multiplied by a frequency multiplier 133 and reset to the original frequency. As a result, the phase regulation range is doubled. Thus it is possible to regulate the phase continuously between 360 deg. and 0 deg.. |
