Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows:
Oscilloscope pre-stage attenuation c...[Details]
Siimpel announced that its MEMS-based silicon camera technology, SiimpelFocus SF9x, has been used in Motorola's newly released MING A1600 mobile phone. The MING A1600 is the industry's first mobile...[Details]
