this is close to a sine wave here. like a single oscillator making a periodic waveform that i can control the amplitude to, which is how loud it is -- louder and softer -- and the frequency of, if i play an octave down, you see, the frequency is how many times per second that waveform vibrates. so in our synthesizers, i can take an oscillator, but i can also change the shape. so you can see that just by varying the way the waveform looks, you can get a lot of different types of sounds. this is a square wave, which is a really recognizable sound in electronic music. this has kind of got a buzzy edge to it, and you can see it's got a lot of harmonic content to it, which means that there's a lot of sines and cosines going out into a high frequency. if i break that down and just add the first sine wave, you see that the major sine wave has a period the same as the square wave, but it doesn't sound like a square wave. now i've added something at twice the frequency, it kind of looks like a molar of a tooth, but you can see

sine curve. it's really a sine curve but a representation of a wave, okay? now, we gonna go through some definitions, gang. this frequency dragged out. the dotted line is my equilibrium point. i'm gonna vibrate above the equilibrium and below, and i go just as far above and just as far as below. i call this particular distance here, by the way-- let's talk about-- let's label these things. what do you call the maximum displacement of a wave? begin with a "a." amplitude. amplitude. you didn't even need the rest part. the other class, i have to say, "begins with the 'a,' ends with a tude." you know, they really go bonkers. okay, put tude. ah, then they get it, okay? we say it's amplitude. so we just put amplitude, "a." a lot of people think amplitude is from here to here. no, no, no, no. that's the peak-to-peak distance, the peak of the wave, the other peak. amplitude is the maximum displacement from the equilibrium position, yeah? - right. - these are just definitions. these are definitions so we can talk about sound meaningfully, and also, so we can talk abo

the questioner asks -- who sine so much more successful than u.s. businesses in your countries? is it true? if so, what's the problem? with corbin. >> i'd say it's not the europeans that we need to worry about. it's the turks, chinese and indians that we need to worry about. the europeans were competitive and the french and british are very active with busy business councils. they're very competitive and they're prepared to go overseas in a way we're only seeing u.s. europeans we need to worry about. i think it's the other countries and we need to be more aggressive and highlight the fact that we have innovation. an example of food. look at 80% of emrites have some form of diabetes. the fact that we have healthy food and diet-conscious products. delmonte just won all sorts of awards. that's because we do things our competitors aren't doing. same thing in health care and other areas where we have a real advantage. i think that's what we have to take on. i don't think it's the europeans. i think it's the other countries that i mentioned that are the problem. >> different view? sam
