摘要： A logical comb filter comprising a logic decision section for making logical decisions on the selection of signals and a signal generating section for generating signals to be selected according to the logical decisions made by the logic decision section. In the signal generating section, a band pass filter extracts from the input of a composite video signal a signal component centering on a color subcarrier frequency, and a first and a second delay line generate three line signals based on an inverted output downstream of the band pass filter. The inverted output is a main signal. The line signals are apart from one another by one horizontal scanning period. The signal generating section further comprises a first mean level calculator for calculating the mean level between the main signal and a first delay signal obtained as the inverted output downstream of the first delay line, and a second mean level calculator for calculating the mean level between the first delay signal and a second delay signal obtained as the inverted output downstream of the second delay line. One of the output signals and the first delay signal is selected by a changeover switch. In the logical decision section, comparisons are made between the three line signals in terms of level and, if the level of the first delay signal falls between the other two signal levels, the changeover switch selects the first delay signal; otherwise the output signal of the first or second mean level calculator is selected in accordance with the level relationship between the three line signals.

摘要： An integrated circuit for boundary scan is achieved to be simple structure. A testing apparatus 6 provides a testing data to a serial input port SI of a integrated circuit IC1 via a external terminal unit 2. The testing data is output to a parallel input port PI of the integrated circuit IC2 from a parallel output port SO of the integrated circuit IC1, then the testing data is output from the serial output port SO. The testing apparatus 6 compares with the testing data outputted to the integrated circuit IC1 and the testing data outputted from the integrated circuit IC2 so that a state of connection is detected between the parallel output port PO of the integrated circuit IC1 and the parallel input port PI of the integrated circuit IC2.

摘要： An adaptively controlled noise reduction device in which an input video signal is supplied to first, second, and third adders and in which an output of the first adder is supplied to the second adder via a memory responsive to a controller whereby the memory provides a controllable delay. An output of the second adder is supplied via a first coefficient multiplication unit having variable attenuation that is controlled by the controller to the first adder as well as via a second coefficient multiplication unit having variable attenuation that is controlled by the controller to the third adder. A change-over switch responsive to the controller outputs either a signal from the third adder or from the memory. Therefore, a signal is output even during the delay period produced by the memory when the signal is delayed between the first and second adders.

摘要： Signal processing apparatus for processing a color video signal formed of a luminance signal and a color carrier signal reproduced from a magnetic tape, in which the signals include respective crosstalk components produced from the tracks adjacent the track being traced. The color video signal was originally recorded so that the crosstalk components are frequency interleaved relative to the signal in the track being reproduced, and signal processing apparatus permits the luminance and color carrier signals to be processed and the respective crosstalk components eliminated using only a single time delay element for both luminance and color carrier crosstalk components. The single delay unit is part of a comb filter and is particularly adapted for fabrication as a CCD element.

摘要： A method of testing an electronic apparatus which eliminates a control signal line for setting an integrated circuit to a test mode and a test mode select terminal of an external terminal section and wherein fetching of test data and transfer of the thus fetched test data are performed in an integrated operation. In each of the integrated circuits, a boundary scan control circuit discriminates a category code at the top of data inputted from a serial input terminal to control a pair of switching circuits. When the category code represents a test mode, predetermined terminals of the switching circuits are selected so that input data are sent out to boundary scan cells. Fetching of parallel data from parallel input terminals and transfer to the boundary scan cells are performed at a time.
