IPC: G06G7/22
Filed: 1980-03-31
Abstract: PURPOSE:To convert the angle signal to trigonometric functions sintheta and costheta with a high precision, by comparing the sawtooth wave signal with the angle signal. CONSTITUTION:Sine wave AC signal (a) from signal generator 1 has the phase advanced by 90 deg., and obtained signal (b) has the zero cross detected to output square wave signal (c), and this signal (c) is converted to sawtooth wave signal (d) by integrator 4. This sawtooth wave signal (d) and angle signal theta are compared with each other by comparator 51 to output square wave signal (e) which rises and falls for the same voltage level, and sampling pulse (f) is generated by monostable multivibrator 52. When sine wave AC signal (a) from signal generator 1 is sampled by sampling pulse (f), output signal (g) of sampling circuit 6 shows  sintheta. The signal (b) phase-shifted by 90 deg. is sampled to obtain output signal (g) of costheta.
