摘要： An apparatus for detecting a tone signal in a telephone switching system is provided in which a calculation, in particular, multiplication is performed by a table look-up process in a digital memory, instead of using a conventional complicated multiplier. A tone signal of a particular frequency in a telephone line is detected through a discrete Fourier transform process (DFT), by the calculation of s(i)=x(iT).times.sin(i2.pi.fT), c(i)=x(iT).times.cos(i2.pi.fT), S=.SIGMA.s(i), C=.SIGMA.c(i), and P=S.sup.2 +C.sup.2. In the above calculation, the multiplication (x(iT).times.sin(i2.pi.fT), and x(iT).times.cos(i2.pi.fT)) is performed by a table look up method in a read only memory (ROM). Thus, the calculation is simplified. Further, the ROM has cells for only the discrete particular levels of multiplicands and/or the multipliers to reduce the capacity of the ROM, and the ROM is referred to by the multiplicand and/or the multiplier through the conversion of the same by a coefficient number generator.

摘要： An apparatus for sending-out orthogonal coordinate signals of a handwritten pattern, in which a handwriting pen is supported by an arm having a variable length with respect to a reference position. The arm is supported by a supporting frame at the reference position to turn with respect to the reference position. The substantial length of the arm from the reference position to the handwriting position is converted to one of the orthogonal coordinate signals. A rotation angle of the arm with reference to a reference line passing through the reference position is converted to the other of the orthogonal coordinate signals. The orthogonal coordinate signals are simultaneously produced with the handwriting operation of the handwritten pattern.
