    摘要: A packaged electronics system, having respective portions each with respective input and output ports, and having interconnection busses between certain of these ports, is tested as follows. Each input port has a set of first transmission gates associated therewith for selectively disconnecting it during testing from the end of each interconnection bus connected bit during normal operation. Each input port has a second set of transmission gates associated therewith for selectively applying test vectors thereto during testing as provided in parallel form from a serially loaded shift register. Each output port connects to the input connections of a respective set of tristate drivers for selectively applying its output signals at relatively low source impedance to at least one interconnection bus connected from the output connections of that set of tristate drivers. A shift register converts the signals appearing in parallel at least one end of each interconnection bus to a concatenation of test results in serial form.

    摘要: A frame synchronizer having broad applicability in television systems is particularly adapted for use in a chrominance time-compressed, luminance bandwidth reduced television system. The frame synchronizer, which separates the composite video signal into its component parts and thereby minimizes the dynamic range required to digitize the signal, demodulates the chrominance signal into its quadrature components and separates the luminance signal. The synchronization signal in the composite video signal generates slave distribution signals and slave horizontal and vertical addresses. The separated chrominance quadrature components and the luminance signal are digitized and, along with the slave distribution signals and the slave horizontal and vertical addresses, are temporarily stored in first-in, first-out memories which provide independent buffering and thereby accommodate a high degree of mismatch between master and slave timing. The chrominance and luminance data are accumulated in distribution registers and transferred to write registers which provide the data input to a frame buffer memory. Master distribution and master horizontal and vertical addresses are generated from a master synchronization signal along with write and read control signals. The data in the write register is read into the frame buffer memory at the slave horizontal and vertical addresses in response to the write control signal, and data in the frame buffer memory is read out from the master horizontal and vertical addresses in response to the read control signal, converted to analog signals, and combined to form a composite signal.
