Tap pants

Tap pants are a form of lingerie designed for women, also known as side-cut shorts or dance shorts, and are similar to French knickers in appearance. As the name implies, they are a type of shorts, in that they cover the pelvic area and the upper part of the upper legs.

Tap pants look much like track shorts, allow freedom of movement, and can be worn as an outer garment over other types of underwear (e.g., g-strings). However, most wearers may wear them as innerwear or leisurewear with nothing underneath. From a distance, one could mistakenly identify tap pants as a half slip.

Name

The name "tap pants" originates from shorts worn by tap dancers during the 1930s, while practicing their routines.

Materials and design

Tap pants are mostly manufactured using materials like lace, silk, satin, polyester, rayon and cotton voile. Some pairs may be trimmed in ruffles.

Popularity

Tap pants have been losing popularity to slimmer versions of underwear since the mid 20th Century, as loose undergarments do not mix with figure-hugging dresses, and especially with pants.

Tap!

Tap! was a magazine for owners of Apple’s iOS devices (iPhone, iPad and iPod touch), published by Future plc. It was a sister title to MacFormat.

Content

The magazine selected and reviewed apps and games from the App Store as well as a range of hardware accessories for iOS devices. There were tutorials on getting the most from your iPad, iPhone or iPod touch, getting started help for those who are new to the platform, and a small section that gives best practice and technical advice to iOS developers.

The last issue of the magazine was published in August 2013.

Finite impulse response

In signal processing, a finite impulse response (FIR) filter is a filter whose impulse response (or response to any finite length input) is of finite duration, because it settles to zero in finite time. This is in contrast to infinite impulse response (IIR) filters, which may have internal feedback and may continue to respond indefinitely (usually decaying).

The impulse response (that is, the output in response to a Kronecker delta input) of an Nth-order discrete-time FIR filter lasts exactly N + 1 samples (from first nonzero element through last nonzero element) before it then settles to zero.

FIR filters can be discrete-time or continuous-time, and digital or analog.

Definition

For a causal discrete-time FIR filter of order N, each value of the output sequence is a weighted sum of the most recent input values:

where:

is the input signal,

is the output signal,

is the filter order; an th-order filter has terms on the right-hand side

is the value of the impulse response at the i'th instant for of an th-order FIR filter. If the filter is a direct form FIR filter then is also a coefficient of the filter .
