Abstract: A signal source from a transmitter is down-converted by being mixed with a locally generated signal so that a desired adjacent channel band is converted to base band and the adjacent channel power measured after filtering by a low pass filter. To eliminate the notch in the filter characteristics that occurs when the power is measured by a.c coupled means, the locally generated signal is modulated or swept around the center of the adjacent channel band.

Abstract: A simulated, parlor-type tennis game in which the type of shot, the direction of travel of a stroked ball, and the direction of player movement are selectively determined by a player, while the distance the stroked ball travels and the distance a player marker is moved along selected paths are determined responsive to a random selector device. A ball bounce indicator is provided to indicate on a playing board an allowable return area after the first bounce of a ball. A ball flight indicator and a player position indicator are positionable on the playing board to indicate the ball flight and player movement respectively. The outcome of a play therefore depends not only on chance, but also on the strategy invoked by the player.
