Function Generators The function generator is a versatile instrument that gives a number of different waveforms at the output with their frequencies that can be adjusted over a wide range. The most commonly used waveforms are sine wave, square wave, triangular wave and the sawtooth wave. Different output signals from the function generator may be available simultaneously. Pic 1 The fig shows the block diagram of a function generator. Here two constant current sources are used to feed the integrator circuit. When the circuit is switched ON, the upper constant current source sends a constant current into the integrator and the output of the integrator is connected to comparator. When the integrator output reaches a predetermined level, the comparator changes the state i.e. the upper constant current source is cut OFF while the lower source is switched ON. This current source passes a current in the reverse direction and the voltage at the integrator output decreases to a pre-determined l...

Know Your Types of box type subwoofer Performance subwoofer to produce low bass sound and also solid course supported by a subwoofer enclosure or box. Subwoofer box in the car usually has a different size, it is adjusted to the recommendations of the technical data from these subwoofers. However, each audio installer, have different styles in a box design. If all this time, we only know when the box was just the type that's all, it did not. Box consists of various types and models. Design, size (dimensions) and a subwoofer box models are usually clearly taken into account at the time of manufacture, even carefully designed too often acted the Installer. Clearly, each type of box has a value of strengths and weaknesses, all models of boxes, if applied correctly, clearly gives a very maximum performance subwoofer. Following this, the types of subwoofer box that is often applied in car audio: If you want us to categorize the type of subwoofer box can be divided according to several or...
