This work involves the design and development of a digital signal detector which is capable of detecting incoming and outgoing signals from mobile phones. The presence of an activated mobile phone can be detected by this handy, pocket-size mobile signal detector from a distance of one and a half meters, which could be used in preventing the use of mobile phones in examination halls, classrooms, confidential rooms etc. The circuit can detect the incoming and outgoing calls, text messages, and video transmission even if the mobile is kept in the silent mode. The moment the gadget detects Radio Frequency (RF) transmission signal from an activated mobile phone, it starts sounding a beep alarm and the Light Emitting Diode (LED) blinks. The alarm continues until the signal transmission ceases. The circuit is assembled on a general purpose PCB as compact as possible. The completed design circuit is analyzed using a multsm software, oscilloscope and multimeter to measure the output voltages across various components when there is or no signal. The results obtained shows how efficient this device can serve the purpose of which it was designed. Officials from West African Examination Council (WAEC) will benefit from the study, since it has been their ambition to stop examination malpractices in Ghana. The study will add up knowledge, both theoretical and practical aspect of electrical and electronic students.

Energy saving methods vary and includes human action (manual operation) and automation (programming). Depending upon the type, mode of operation can significantly provide a unique way of saving energy. This research presented a proposed smart energy saving system using a PIR sensor in a classroom; this uses infrared (IR) remote control system to switch „on‟ or „off‟ an energy system in the absence of human beings. Satisfactory results of signal transfer from the remote control to the fan and light was achieved. The circuit consists of PIR and Temperature sensors, and a microcontroller-based automation along with a temperature and motion display using LCD to switch „on‟ and „off‟ fan and light circuits. An embedded system was employed in constructing the energy saving system. Four different softwares were used for the testing to authenticate the performance of the work. They are Windows operating system (windows 7), Cadsoft EGLE software, Multism software and Hyper terminal (arduino 1.6.3). The testing was done with an intelligence signal at different stages. The test results indicated a successful implementation of the work compared. The device is made up of two sensors, and a time delay of 10mins. More than two sensors can be used to achieve more clearance and a time delay of 60 seconds. The findings of this research will be very meaningful to many stakeholders.

The main purpose of the study was to evaluate the impact of well-equipped Applied Electricity laboratories in the teaching of Applied Electricity for competency based skills acquisition in Senior High Technical Schools, using Tsito Senior High Technical School as a case study. The researcher used descriptive research design for the study. The study used quantitative and qualitative research approach. The total population for the study was 32 students and 5 teachers totaling 37 in all. Purposive sampling techniques was used to select all the 37 respondents for the study. Data was collected using a structured questionnaire and an interview guide. Primary data was collected through a field survey from teachers and students of the Tsito Senior High Technical School. The edited responses were recorded and analyzed statistically. SPSS version 18 was used to analyze data. The study results concluded that the school does not have enough teaching and learning materials to facilitate the teaching and learning of Applied Electricity. Moreover, student’s interest and class participation was high in Applied Electricity class when the teacher used TLMs. The study recommended that the Ghana Education Service through the District Education Office should supply adequate educational resources and Teaching and Learning materials (TLMs) to equip the schools Applied Electricity Laboratory and enhance the teaching and learning of Applied Electricity in the school.

Fiber backbone is almost at the verge of replacing the microwave link completely owing to the high demand for capacity. To achieve this high capacity with fiber in other to reduce complaints of poor quality of service, proper deployment techniques must be employed by network operators. This project delves into the network elements, their installations and their interconnection topologies of the various fiber backbones deployed by all the network operators in Ghana. The analytic method was used for the work. Link budget analysis was done over the existing links of the backbone of all the network operators to obtain the losses in the links. After the analysis it was observed that the duct method of installation had lesser losses than the direct buried method due to it being less prone to fiber cut. Both duct and direct buried methods of installation should be used depending on the environment between two nodes. This will help cut down the cost of installation. Also engineers should comply with regulations on deployment. They should ensure that factors which will lead to a reduced performance of the fiber such as poor termination of the cable, splicing fallen outside its defined range of 0- 0.05dB, shallow burial depth, bends, absence of warning tapes and poor laying of cable are avoided.
