Off spin Off spin Off spin is a type of finger spin bowling in the sport of cricket. A bowler who uses this technique is called an off spinner. Off spinners are right-handed spin bowlers who use their fingers to spin the ball from a right-handed batsman's off side to the leg side (that is, towards the right-handed batsman, or away from a left-handed batsman). This contrasts with leg spin, in which the ball spins from leg to off and which is bowled with a very different action. A left-handed bowler who bowls with the same action as an off spinner is
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
