Leg break the batsman's legs are usually in the path of the ball if it misses the bat or takes an edge. This makes it difficult for the bowler to get the batsman out bowled or caught from a leg break. A ball bowled by a left-arm unorthodox spin bowler with a leg break action spins in the opposite direction, i.e. from left to right as the bowler sees it. Such a ball is not normally called a leg break but a "left-arm unorthodox spinner" or "Chinaman". Leg break A leg break is a type of delivery in the sport of cricket.
Square wave in very sensitive circuits such as precision analog-to-digital converters, sine waves are used instead of square waves as timing references. In musical terms, they are often described as sounding hollow, and are therefore used as the basis for wind instrument sounds created using subtractive synthesis. Additionally, the distortion effect used on electric guitars clips the outermost regions of the waveform, causing it to increasingly resemble a square wave as more distortion is applied. Simple two-level Rademacher functions are square waves. The square wave in mathematics has many definitions, which are equivalent except at the discontinuities: It can be defined as
