Abstract: A connection member of simple structure having a high reliability and capable of performing electric cable branching is provided. Connection portions of a plurality of electric cable terminals having an electric cable are respectively inserted into an electric cable terminal insertion hole of a holding body. Cylindrical contact points of the connection portions are aligned in a pin terminal insertion hole and a pin terminal is inserted into the pin terminal insertion hole. The pin terminal is successively inserted into the cylindrical contact points of the electric cable terminals arranged in parallel in the pin terminal insertion hole so that the pin terminal is electrically connected to the plurality of connection portions and the connection portions are short-circuited with one another.

Abstract: An A/D converter comprises a first reference voltage source generating a first group of reference voltages distributed in a first voltage range, and a first A/D converting circuit connected to receive an analog signal and the first group of reference voltages for generating a first digital signal. The A/D converter also includes a second reference voltage source having a bias input receiving a bias voltage and generating a second group of reference voltages which are distributed in a second voltage range smaller than the first voltage range and which are biased by a bias voltage inputted to the bias input, and a second A/D converting circuit connected to receive the analog signal mentioned above and the second group of reference voltages for generating a second digital signal. A calculator is provided to receive the first and second digital signals for generating a third digital signal having a resolution higher than that of the first digital signal.

Abstract: In a signal processing device, such as a television receiver, a multiplex signal processing circuit with a switching device for selecting either a first image signal and a second image signal. A clamping circuit is provided for clamping the pedestal potential of the second signal at a reference voltage, a comparator compares the pedestal potential of the first signal with the reference voltage, and the pedestal potential of the first signal is equalized to the reference signal in accordance with the comparator output.
