Designing Class a Colpitts Oscillator and Analyzing the Effect of DC Power Supply on its Frequency Stability ijtsrd
Oscillator circuit is one that converts DC power into AC power at a frequency without any input signal. Oscillators are commonly used in communication systems to generate carrier frequency ranging from audio frequency 20 Hz to radio frequency 100G Hz . There are two main classes of oscillators, harmonic oscillator with sinusoidal output e.g. sine […]

Software Engineering Cost Estimation using COCOMO II Model ijtsrd
Estimating the software cost and price to customer is vital role for software engineering. Accurate Software development cost estimation is important for effective project management such as budgeting project planning and control. Before software development processes begin, software cost and duration for any project should be agreement between developers and customers.In this paper, the effort […]
Design and Simulation of Power Factor Correction Boost Converter using Hysteresis Control ijtsrd
Nowadays various power converters like AC DC or DC DC are widely used due to their flexible output voltage and high efficiency. But these converters take the current in the form of pulses from the utility grid so that the high Total Harmonic Distortion THD and poor Power Factor PF are the major disadvantages of […]
