Filed: 1988-07-25
Abstract: PURPOSE:To use a high sampling frequency and to increase the maximum output frequency by executing a phase-amplitude conversion based on an instantaneous phase value obtained by interpolating mutually the output of respective phase accumulators with an interpolating means. CONSTITUTION:When a phase accumulator means 1 is composed of two phase accumulators 111 and 112, an initial value setting means 13 executes the initial value setting to an accumulator 111 so that the initial value can be '0' and the increase rate for the input of a clock CLKa can be two times (2N) as much as the frequency setting data N. For an accumulator 112, the initial value setting is executed so that the initial value can be N and the increase rate for the input of a clock CLKb can be 2N. When a clock CLKc input is '1' level, an (a) input from the accumulator 111 is outputted, and at the time of a '0' level, a (b) input from the accumulator 112 is outputted. When the period of clocks CLKa and CLKb is DELTAt, the interpolating means 12 outputs (interpolate-outputs) an instantaneous phase value with the period of the clock as DELTAt/2. Namely, in the interpolating means 12, it is equal to the fact that the clock frequency two times as much as respective accumulators 111 and 112 is used.
