2009-01-31T10:50:00.000-08:00

M-files allow you to type in all the commands into one file before you run them. These files are similar to those created in C++ before you compile them.Through M-files you can also create functions that will run like the internal functions in Matlab. And if you find it very hard to understand, the help menu will cover all. he heGetting Started:1. To get started open your version of Matlab.2.

What is a fuel cell?

2009-01-30T09:43:00.000-08:00

A fuel cell is a device that generates electricity by a chemical reaction. Every fuel cell has two electrodes, one positive and one negative, called, respectively, the cathode and anode. The reactions that produce electricity take place at the electrodes.Every fuel cell also has an electrolyte, which carries electrically charged particles from one electrode to the other, and a catalyst, which

Frequency Hopping

2009-01-30T00:42:00.000-08:00

Frequency Hopping Functions:1. Frequency diversityFading features on different frequencies are different. So we can decrease the effects of Rayleigh fading by using frequency hopping.2. Interference diversityInterference on a certain frequency can only affect the signal in a short period of time because the frequency is hopping rapidly among the MA. The interference is divided evenly among all

Iseng bikin RFID sederhana,Gambar rangkainnya bisa di samain.Kalo sistem ini pake reader ID-12 yang dilengkapi dengan internal antenna, dan mempunyai jarak baca antara 12 cm – 16 cm. Apabila ditambahkan dengan external antenna, maka maksimum jarak baca bisa bertambah sampai 25 cm. ID 12 juga mempunyai tiga jumper yang ketika power-up akan di cek keadaannya untuk menentukan format mode output yang
