Three-Phase Transformers

Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.

Transformer

Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.

Question

Q 2:
A sinusoidal signal v (t) =5 Cos (2 nt) is transmitted using a 5-bit binary
PCM system. The equalizer is of a midrise type, with a step size of 2 volt.
1. Sketch the quantizer curve ( input -output )
2. Sketch the PCM wave for one complete cycle of the input;
assume a sampling rate of four samples per second, with
samples taken at t=+1/8, +2/8, +3/8, ±4/8 .
3. Determine code words at the time instants t=+1/8, ±2/8, +3/8,
+4/8
4. Determine the minimum step size for delta modulation of the
sinusoidal signal v (t) = 5 Cos (2 t) which is required to avoid
slope overload (assume sampling = nyquist rate).
5. Compare between PCM and delta modulation.
