Title: Digital signal processing system
Inventor: IDEI TOSHIO
IPC: H03H17/00
Filed: 1984-09-18
Abstract: PURPOSE:To simplify the constitution of a circuit and to obtain twice the gradation number under the same number of bits by extracting only a positive or negative half-wave of an input AC analog signal by an A/D conversion circuit, superposing a signal obtained by inverting the polarity of the extracted signal and delaying by a prescribed phase to the output signal of a D/A conversion circuit and extracting the superposed signal as an output AC analog signal. CONSTITUTION:Although an AC analog signal shown in Fig. (a) is converted into a digital signal by an A/D conversion circuit 2, only the positive half-wave of the input AC analog signal is extracted and converted into the digital signal because the 1st and 2nd reference voltages VH, VL are set up to the positive maximum amplitude value of the input AC analog signal and its average zero level value respectively. The converted digital half-wave signal is properly and digitally processed by a digital processing circuit 3 and the processed signal is inputted to a D/A conversion circuit 6 to execute the D/A conversion of the input signal. Since only the positive half-wave is A/D converted, twice the gradation is obtained as compared to the ordinary method having the same number of quantizing bits. Therefore, the number of quantizing bits for A/D conversion is reduced by one bit if the gradation number may be the same as that of the ordinary method.

Since the digital signal is formed by using an up-down counter, the recurring frequency (fundamental frequency) of the digital signal is recognized in advance. Thus, the timing signal of the digital low pass filter 43 is formed easily.

Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To easily design and manufacture an electric interpolation device by constituting part of an electric interpolation means so that a plurality of blocked circuit boards can be mounted on a different circuit board and making an interpolation value selectable in accordance with the number of the mounted circuit boards. SOLUTION: A phase shifting circuit 5 generates (m) sets of sine wave-like signals from two sine wave-like signals having phases of, for example, 0 deg. and 90 deg. from an encoder head HE and inputs the signals to (n) divided circuits boards 1-1 to 1-m. The circuit boards 1-1 to 1-m respectively generate rectangular wave signals having different phases obtained by dividing one period of an input signal by (n). Interpolation of 1/(n×m) is substantially realized by processing the rectangular wave signals by means of the logic circuit of an interpolation signal forming circuit 7. A detection circuit 6 outputs a select signal for selecting the interpolation signals corresponding to the number of existing n-divided circuit boards to an AND gate AN upon obtaining mounting detecting signals from the n-divided circuit boards.  Therefore, the number of kinds of circuit boards can be minimized, because a selected interpolation signal is outputted from an OR gate OR and a plurality of divided circuit boards can be selected on a common circuit board.
