Operational amplifiers (Op Amp) have been in use for quite a long a long time now in the field of electronics and electrical engineering. A basic Op Amp has got three connections consisting of 1 output and 2 inputs. For definition purposes the two input terminals are called inverting and non-inverting inputs (Huijsing, 2011). Huijsing (2011) adds that it has been found and proven that when the voltage at both points of the inputs is the same, there will be no output on the other side. The image below

Recent Research In March 2014, G. Ivanovs and V. Bobrovs [9] investigated the characteristics of (EDFA) Erbium doped fiber amplifier where The amplification and fiber depends on different EDFA parameters.A 2.5 Gbit/s one channel WDM transmission system were simulated and measured. Additionally, simulation of a 4 channel 2.5Gbit/s WDM system was also done containing in-line amplifiers to investigate the EDFA performance for multichannel system. As they obtained almost identical result of simulated and

will also only help in rehabilitation of blind individuals all around the world especially in poor countries where rehabilitation is quite limited to specific individuals. Significant components used are IR emitter, IR receiver, potentiometer and amplifier to form prime photo-electric sensor. Along with it DC battery, power switch and buzzer is connected in the blind stick. A photoelectric sensor is a device that senses a change in light beam intensity. Characteristically, this means either non-detection

ins and outs of the physical realm within the music world. I want to know how the amplifiers that I use on a day to day basis function.

) Description of the HPGe gamma-ray spectrometer A high resolution gamma detection system was used for gamma analysis. This system consist of an ORTEC hyper pure germanium detector (HPGe), model number GEM- 15190, coaxial type detector with a serial number 27-P-1876A recommended operating bias, negative 3 Kv. The detector used has crystal diameter 49.3 mm, and crystal length 47.1 mm. The HPGe detector has a full width at half maximum (FWHM) 0.9 keV at the 122 keV gamma transition of Co-57 and 1.9

Taking guitar lessons can be fun, yet challenging. It is beneficial to find a teacher for one on one classes or drop classes to start learning the basics. In this article we will list a few places you can take lessons. A2G Sharp Guitar is a great place for lessons. There philosophy is simple Learn and have fun! They teach a balanced approach to mastering the guitar. They teach the basic fundamentals of the guitar all the way up to advanced. This place comes highly recommended for lessons. For more

what’s up?” He was standing behind a glass counter filled with guitar pedals. “Anything you’re looking for in particular?” I do a quick scan around the room. “No I just heard about this place and wanted to check it out.” The walls are lined with amplifiers,

Abstract: Energy efficiency (EE) is an important objective in uplink wireless communications due to the limited capacity of batteries in user equipment (UE). Consider the scenario in which the access point (AP) serves a subset of UEs when available resources cannot support all of the UEs’ quality-of-service (QoS) requirements. In this project, propose a scheduling metric to balance the tradeoff between EE and fairness. Based on the scheduling metric, propose a suboptimal joint scheduling and resource

installed correctly and operates at its optimum level will allow a sound signal to travel from one or more microphones to a mixing console. At the mixing console all signals will be mixed together in the right balance and levels and sent out to an amplifier. The signals are then converted into much larger signals and sent to the speakers creating sound waves for the audience to hear.
