Improvements in electronic circuits for the production of spin - stoe sen in the case of character display systems of the luminescent screens, in particular for led's screen games

摘要

An electronic circuit is disclosed, of the kind used in simulated television games, in which the positions of certain symbols representing objects necessary to the performance of a game, such as the pads and the ball for simulating a table tennis or lawn tennis game, are governed by the players through the manipulation of circuit controlling knobs, the improvement consisting in that supplementary circuit means are provided to render the display of the positions of certain symbols more accurate and detailed. For example, it is possible, by adopting the supplementary circuit means of the invention, to display not only the position of a table tennis ball relative to the pads and the game field, but also to simulate certain refinements of the game, in the case in point, to simulate spin strikes impressed to the ball, smash strikes and the like. The improvement also involves a more realistic acoustical simulation of the strikes imparted by a pad to the ball.
