Abstract: An IC testing apparatus has a detecting circuit for detecting an inversion of an output state of a test output from an IC under test in response to application of a clock signal, a comparing circuit for comparing a value preset in a storage circuit with the output state of the test output and an output state of the detecting circuit. In a first comparison operation, the number of pulses of the clock signal applied to the IC under test is less than the number of pulses required to invert the output state of the test output by one pulse and the test output and detector output are compared with corresponding values preset in the storage circuit at times coincident with a test strobe signal synchronized with the clock signal. In a second comparison operation, another clock pulse is applied to the IC under test to make the total number of pulses equal to that needed for inverting the test output and the above comparisons are again made with corresponding preset values.

Abstract: A recording device records the speed data as a binary number by using a first byte and a part of a second byte, and records the sampling number as a binary number by using the remaining part of the second byte when the number of digits of the sampling number is not greater than the number of bits of the remaining part of the second byte, while recording low-order digits of the sampling number as a binary number by using all the remaining part of the second byte and recording high-order digits of the sampling number and information for indicating record of the high-order digits of the sampling number by using a third byte when the number of digits of the sampling number becomes greater than the number of bits of the remaining part of the second byte.

The data recording device further includes a device for detecting an inflection point of the data sampled by the sampling device, wherein when the inflection point is detected by the inflection point detecting device, the compression processing is stopped.

Abstract: A vehicle speed measuring method and apparatus which can cope accurately with several vehicle speed sensors which produce different numbers of pulses for one rotation. Such vehicle speed sensors prepared for the method and apparatus produce predetermined different numbers of pulses for one rotation, some of such sensors defining a group wherein such numbers of pulses have a greatest common divisor greater than 1. It is first determined whether or not a particular vehicle speed sensor employed belongs to this group of sensors. When the sensor belongs to the group, pulses therefrom are frequency divided by a value obtained by division of the number of pulses produced for one rotation of the sensor by the greatest common divisor, and time data indicative of the time of appearance of a pulse by frequency division are stored into a memory for one rotation of the sensor.
