Leg break Leg break A leg break is a type of delivery in the sport of cricket. It is a delivery of a right-handed leg spin bowler. A leg break is bowled by holding the cricket ball in the palm of the hand with the seam running across under all the fingers. As the ball is released, the wrist is rotated to the left and the ball flicked by the ring finger, giving the ball an anti-clockwise spin as seen from behind. When the ball bounces on the pitch, the spin causes it to deviate towards the left from the bowler's perspective;
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
