In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
IdeaPad (stylized as IDEAPΛD and formerly ideapad) is a line of consumer-oriented laptop computers designed, developed and marketed by Lenovo. The IdeaPad mainly competes against computers such as Acer 's Aspire , Dell 's Inspiron and XPS , HP 's Pavilion , Envy , Stream , and Spectre , Samsung 's Sens and Toshiba 's Satellite .
The IdeaPad tablets from Lenovo were a brand of consumer-oriented tablet computers designed for home use or entertainment, as opposed to the business-focused ThinkPad Tablet series. [1] Devices sold in certain countries, such as China, India and New Zealand, were sold under the LePad brand, similar to the LePhone series of smartphones .
Oddly, because Lenovo is kind of known for making ugly but incredibly usable keyboards. Yet the Yoga 13 has a half-sized backspace and right shift key, which means I mistyped a lot. When you're in tablet mode, there's the Windows 8 on-screen keyboard, which, due to the Yoga 13's huge screen (compared to other tablets), is great.

The IdeaPad S10 was Lenovo's first netbook. [4] While Engadget found the design unremarkable, the low starting price was well-received. [4] The S10 featured a 10.2-inch (260 mm) TFT active matrix 1024×576 or 1024×600 display with an 80 or 160 GB hard disk drive and 512 MB or 1 GB DDR2 Random Access Memory, both of which could be upgraded via a trap door on the bottom of the netbook.
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
