Signal amplification circuit The ultrasonic signal which was received with the reception sensor is amplified by 1000 times(60dB) of voltage with the operational amplifier with two stages. It is 100 times at the first stage (40dB) and 10 times (20dB) at the next stage. As for the dB (decibel)‚ refer to "Logarithm Table". Generally‚ the positive and the negative power supply are used for the operational amplifier. The circuit this time works with the single power supply of +9 V. Therefore‚ for the

Investigation of Wireless Measure and Control Methodology for High Voltage Circuit Breaker I. INTRODUCTION The high voltage circuit breaker is the most important device for protection and control in power systems and its safety operation has always been an important requirement to be guaranteed. The working state of high voltage circuit breaker can be evaluating by the condition monitoring and fault diagnosis technology. If the data provided by the condition monitoring proved to be normal‚ the

The old telephone system (PSTN) uses circuit switching to transmit voice data whereas VoIP uses packet-switching to do so. The difference in the way these two types of switching work is the thing that made VoIP so different and successful. To understand switching‚ you need to realize that the network in place between two communicating persons is a complex field of devices and machines‚ especially if the network is the Internet. Consider a person in Mauritius having a phone conversation with another
