IPC: H03M1/32
Filed: 1985-12-06
Abstract: PURPOSE:To record a waveform at low cost by digitizing directly the waveform on the tube surface of an oscilloscope. CONSTITUTION:A bright line normally extends to both side parts of the tube surface of a CRT 1 and a contact type linear image sensor 2 is fitted vertically thereto, so that vertical bright line position information 10 is obtained. Further, a D/A converter 7 which outputs a horizontal axis position variable voltage is utilized to make a right-to-left shift in position and then the position of the vertical axis of the tube surface waveform is detected corresponding to the horizontal axis position. Namely, while the horizontal axis position is shifted, the bright light position of the vertical axis is detected to obtain coordinate information on the tube surface waveform. When this obtained coordinate information is weighted, time slice information 8 on the horizontal axis is received by a microcomputer 8 from a sweep generator 6 and vertical axis voltage slice information 14 is received from a vertical axis attenuator 13; and they are converted. The weighted waveform information is passed to peripheral equipment (e.g. printer) 15 through a bus 12, so that the waveform can be recorded.

IPC: G05F3/08
Filed: 1985-12-06
Abstract: PURPOSE:To obtain not only an optical output voltage but also a larger output voltage than an input voltage, by providing a voltage dividing means for generating two voltages of an optional ratio from a single input voltage, and a dividing circuit for executing a dividing operation of two voltages and obtaining as its output an output voltage corresponding to a denomenator input and a numerator input. CONSTITUTION:When a non-stable input voltage e1 is impressed between input terminals 1, 2, an electric current flows through a resistor Rv and a voltage e1' is generated, e1 and e1' are inputted to a dividing circuit and a dividing operation is executed, and in case the voltage e1 has become a denominator input, an output voltage e2 corresponding to e1'/e1 (<1) being a result of division appears between output terminals 3, 4. Also, when the denominator input and the numerator input which are impressed to the dividing circuit are reversed so that a result of division becomes e1/e1' (>1), the output voltage e2 can be obtained as a larger value than the input voltage e1. In such an operation, even if the input voltage e1 is varied, a ratio e1'/e1 or e1/e1' of two voltage which are generated is constant, therefore, the output voltage e2 becomes stable irrespective of a variation of its input voltage.
