The University of Eldoret is one of the 22 public universities in Kenya and located approximately 9 km from Eldoret town, Uasin Gishu County. It was … Read more

3.6 Waveform generators 3.6.1 Triangular wave generator A triangular wave generator can be formed by simply connecting an integrator to a square wave generator. The resultant circuit is shown in Figure. This circuit requires dual op-amp, two capacitors, and at least five resistors. Triangular wave generator The frequencies of the square wave and triangular wave … Read more

2.4 AC characteristics For small signal sinusoidal (ac) applications, one has to know the ac characteristics such as frequency response and slew rate. Frequency Response of an OP-Amp Ideally an open loop op-amp has infinite Bandwidth. It means that, if its A0L = 90dB with dc signal its gain should remain the same 90dB through … Read more

There are two types of error coefficients such as: 1. Static error coefficient 2. Dynamic error coefficient Static error coefficient Ability of the system to reduce or eliminate the steady state error is static error coefficient. It is of 3 different types. 1. Position error coefficient:- Here the reference input signal is a constant (step … Read more

1. Let us derive the recurrence equation for Fibonnocci series and perform complexity analysis for the same. The fibonacci numbers are given by the series: 0, 1, 1, 2, 3, 5, 8 defined by the simple recurrence (i.e.) F(n) = F(n-l) + F(n-2) for n > 1 ….(1) and two initial conditions are F(0) = … Read more

Discussion Software testing is a vast field which is performed with the sole objective of finding defects in system under test. The question is to what all techniques can be used to test and the importance of these techniques is researched. Techniques like Black box, white box and grey box are prevalent to find the … Read more

1.3 Multipath propagation Effects of multipath propagation in cellular network: 1. Multipath Propagation: For wireless communications, the transmission medium is the radio channel between transmitter TX and receiver RX. The signal transfers from the TX to the RX via number of different propagation paths. In some cases, a Line Of Sight (LOS) connection might exists … Read more

1 Introduction Underwater technologies has recently gained an increasing research attention. This is mainly due to the recent increase in exploitation of natural resources underwater along with the ongoing trend on collecting big data from underwater enviroments through Internet of Underwater things (IOUT) [kiko,Gussen,Jiang]. Also, such technologies would support multiple ocean applications such as: oceanographic … Read more

Picture Archiving and Communication System (PACS) is a system for radiologists at the hospital which allow them to see filmless images of patient’s X-rays, MRI, etc. PACS has become a big part of the health industry as more hospitals use this system to read images, not only is it in the radiology department, but it … Read more

There is a critical need for improving the authentication standards because of breaches being caused by weak usernames and passwords. With more than 60% rise in credential thefts and violations occurring across global major corporate organizations, second factor authentication is a must cite{Ref1}. To address these concerning issues, the FIDO alliance launched a new protocol … Read more
