The circuit uses a light emitting diode to display the difference frequency of the two-color oscillator. Only one LED can be lit at a time, and if there is a significant rotation of the point, there is an indication of the best frequency. When f1 is greater than f2, the spot rotates clockwise, and vice versa, rotates counterclockwise. When f1 is equal to f2, the spot does not rotate.
Floating Board To Board Connector
FLOATING Board to Board Connector
FLOATING Board-to-board (BTB) connectors as the name indicates is used for connecting circuits board together. This kind of connectors are suitable for stacking circuits boards one over another. Flat flexible cables can be avoided using these kinds of connectors; moreover it makes the entire unit more compact. The commonly used BTB connectors are SMT connectors and Berg Strip. We will discuss about them in detail in the following section.
SMT CONNECTOR
Surface Mount Technology (SMT) connector is a commonly found board-to-board connector in advanced circuit boards. As the name indicates this connector is available only in surface mount model. It is carefully mounted on to the solder pads on the surface of the PCB.
SMT connectors are ideal candidate for miniaturization due to their small area of occupancy and stacking height. They are suitable for double layered or multilayered PCBs. They are designed for high performance and reliability.
They commonly found in advanced circuit boards in networking equipment, telephones, mobile phones, computers and other consumer electronics.
