Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry can be modified for improved operation at 433.92MHz, a frequency commonly used in Europe. Twoalternative match and filter configurations are presented: one for optimizing drain efficiency, the other for achieving higher transmitpower. Features and capabilities of earlier Maxim industrial, scientific, and medical radio-frequency (ISM-RF) transmitters areprovided, allowing comparison of the MAX7060 to its predecessors. Several design guidelines and cautions for using the MAX7060are discussed.

Writing Your First ASP Application ( Quick Start ) (Page 1 of 8 ) There are many tutorials out there that show you how to program in ASP. Some of them are good, and some are bad. Some of them are downright terrible. In any case, you ve read a bit about ASP and now you are ready to build your first application. But where do you start? In my own experience, I have found that I find it easier to learn something if I actually work with it hands-on. Just reading a book or documentation doesn’t give you the practical knowledge you need to be able to rush off and start creating applications. In this article, I will discuss the creation of a very simple application. I will cover what the application will do, how we will approach writing it, demonstrate in code how we will do it, and discuss additional features that could be added to it.

map identification laquo yuan Problem description : the digital image processing of an image often expressed as a macute M pixel matrix. Each pixel value is 0 or 1. The value of 0 pixel image, said background, and the value of a pixel image, said a map of a million, usually called map million pixels. When a pixel in another pixels above, below, left or right, said that two adjacent pixels of the pixel. An image of the pixels belonging to the same map yuan, instead of adjacent pixels belonging to different map yuan. Figure yuan identification of problems is right for the given image pixel map marking yuan, making the same map billion yuan pixel map of the same markings and different map billion yuan pixel map of their marks are different.
