Design of a Motor Speed Sampling, Amplification, Filtering and Display Essay - 1

Design of a Motor Speed Sampling, Amplification, Filtering and Display Circuit - Essay Example Based on the requirements of the course, it is mandatory that the current signal be converted between the ranges -2.5 mA to 2.5 Ma and through a voltage signal ranging between the voltages of 2 V to 3 V. When all the recommended conversions have been done, then it is advisable that any noise that may be available be suppressed in AC signals that have frequencies that exceed 100 Hz. When all these have been carried out, the analogue circuit is converted into digital signals and A to D converter is maintained at 8 bit. The 8 bit of the digital signal is then relayed onto the 7-segment for display. The converter finally gives the ADC clock of the whole system. This course work may be analyzed based on two major components. These components include analogue circuits of the system and the digital circuits of the system. The analogue circuits of the system operate on signals of low currents that are meant for conversion to the voltage signals. The noise is then filtered out from the signals of the AC. The analogue circuit consists of the following parts thus, rectifiers, low pass filters, and the amplifiers (Gieras & Wing 2002). The rectifiers are used to convert alternative current voltages into the signals of direct current voltages, the low pass filters are used to filter the noise that might be present in the alternative current voltage signals that have been amplified, and finally, amplifiers are used in the amplification of the small signals of the currents into the required voltage signal ranges. The part of the digital circuit is categorized into the following thus, converters classified as A to D, the 8-bit synchronous counter, and decoders classified as BCD and SSD. The D to A converters are used in the conversion of the analogue circuit signals to the digital circuit signals. The converter feeds the ADC clock of the system. BCD to SSD converters are used

To what extent are current approaches to the management of workplace Essay

To what extent are current approaches to the management of workplace stress; work life integration and equal opportunities successful in addressing these issues - Essay Example Solving the real problems in the work field like hiring better employees, enhancing work motivation, increasing job satisfaction, promoting safety attitudes, reducing absenteeism and accidents form part of better organisational outlook towards better management. (Arnold, J.et al, 2005) Stress is purely related to the involvement of the self with the environment. Can a corpse have stress over its burial or cremation? Thus stress is concerned with the movements of life that lays its impact on perception differences. Many stimuli, psychological, social and even physical are stressors only if they are perceived as stressful. (Stephen M. et al, 2001) Work-life integration involves appropriate management adoption in the life styles and work fields. The factors destabilising the balance are prone to emerge both at work place and at the family environment. The role of a staff in striking the balance between work place stress and family level management is normally and abundantly dependant upon the situations at the work place environment. A husband’s inappropriate fury over paltry family issues is to be borne by the family members or wife giving importance to the work place stress of the bread winner. Absence of such endurance at family level causes certainly an imbalance in the minds of the working people causing unwanted results both at work place and family. Imbalance at work place has its impact on the outcome of his/her job, which is production capability. Equal opportunity is the best tool for an employer to bring as much work force in to his umbrella as possible to be considerably productive. The same is also the tool for the employees to get their fundamental rights fulfilled, which simultaneously pave way for trade unions to become the middle force to get the staff welfare profusely maintained. As this factor permeates between both employees and employers, attainment of perfect equilibrium is often elusive. The part of employers
