Abstract In this assignment‚ lead compensator is implemented to reduce the percentage of peak overshot to less than 5% and the settling time to 2 second with 2% accuracy. First of all‚ to implement lead compensators into a circuit‚ a pole–zero pair is introduced into the open loop transfer function. Lead compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. Besides that‚ it also provides phase lead in its frequency response

CIRCUIT IDEAS FUEL RESERVE INDICATOR FOR VEHICLES D. MOHAN KUMAR ere is a simple circuit for monitoring the fuel level in vehicles. It gives an audiovisual indication when the fuel level drops alarmingly below the reserve level‚ helping you to avoid running out of petrol on the way. Nowadays vehicles come with a dash-mounted fuel gauge meter that indicates the fuel levels on an analogue display. The ‘reserve’ level is indicated by a red marking in some vehicles‚ but the needle movement through

transmitter-receiver is indeed an electronic project that places great emphasis on practical work. The project enhances one’s practical skill and it involves both the electronics and telecommunications fields. Theoretical knowledge such as circuit theory‚ amplifier and principles of telecommunication learned through several courses offered by the Electronics and Telecommunications program is applied in the project. A set of handset-size transmitter and receiver is constructed. This wireless communication

For our project we decided to disassemble and understand a Memphis 1 Channel Mono Block Amplifier. First we started by disassembling the amp down to the main circuit board. From there we assigned ourselves different components to understand what they were and how they worked inside the amp. We all researched our components and got back together to discuss and figure out the flow of power and operations of the amp worked. A general idea of what the amp does is as follows. Power comes into the inputs

Electric string instruments use electrical signals and amplifiers to increase an instrument’s volume and modify its sound. Composers from all genres of music have used electric instruments in their compositions. While electric instruments more commonly appear in rock and popular music the classical composer George Crumb wrote a composition for electric strings entitled “Black Angels.” Electric string instruments are not the same as semi-acoustic instruments that use a mixture of sound boxes and electric

Amplitude modulation is when the modulating audio is combined with a radio frequency carrier is such a way that the total wave power is made to vary in accordance with the modulating audio. The normal type of AM is double sideband or‚ to be more specific‚ double sideband full carrier. Recall that the carrier does not convey any intelligence
