Leg spin Leg spin Leg spin is a type of spin bowling in the sport of cricket. A leg spinner bowls right-arm with a wrist spin action, causing the ball to spin from left to right in the cricket pitch, at the point of delivery. When the ball bounces, the spin causes the ball to deviate sharply from left to right , that is, away from the leg side of a right-handed batsman. The same kind of trajectory, which spins from right to left on pitching, when performed by a left-arm bowler is known as left-arm orthodox spin bowling. As with all
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
