represents‚ either 0 or 1. Digital signals are complex waveforms that can be described as a discontinuous waveform having a finite range of levels. You can recognise a digital signal by the wave created‚ if the wave keeps going up and down in straight lines and forms squares and rectangles these are digital signals. Digital signals assume two states (logic 0 and logic 1). Where the signal changes from one state to another‚ the signal can be said to be discontinuous. As the signal state changes from

Yes‚ an automatic transmission calculates the gear ratios and does the shifting for you but where’s the fun in that? That’s like playing a video game that shoots all of the targets for you. Driving a manual transmission is having full control over one of the world’s most powerful machines. Wouldn’t you want better gas economy without sacrificing horsepower? The beauty

The idiom “there are plenty of fish in the sea” is not literally true. In fact‚ the documentary‚ The End of the Line‚ has estimated that by approximately 2050‚ there will be no fish in the sea. Overfishing is a serious issue that involves taking wildlife at increasingly higher rates than the species can replace. Because this issue is hidden under waters‚ people do not realize the seriousness nor do they realize the consequences. This film highlights some of the well-known species‚ such as bluefin
