Cover drive (cricket) Cover drive (cricket) The cover drive in cricket is the act of stroking the ball through the covers with well-timed wristwork and conventional movement of the front foot toward the pitch of a delivery aimed at or outside the off stump. The cover drive is considered one of the most graceful shots playable in the sport. Batsmen able to master the cover drive are usually given especially high praise because of the shot's difficulty in execution and its requirement for exquisite timing. When played to perfection, the cover drive comprises a batsman's seemingly effortless wielding of the blade in a
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
