Orient Electric Diploma Electrical Engineer Interview Questions and Answers

An analog signal is a continuous signal that represents information using a continuous range of values.

• Analog signals can take on any value within a continuous range.

• Examples of analog signals include voltage, current, and sound waves.

• Analog signals are used in many electronic devices such as radios and televisions.

Diagnosing circuit diagrams involves analyzing components, connections, and signals to identify issues or faults.

• Identify all components in the circuit diagram

• Check for proper connections between components

• Analyze signal flow through the circuit

• Look for any short circuits or open circuits

• Use tools like multimeters for testing components

A power supply circuit diagram is a visual representation of the components and connections used to provide electrical power to a device.

• Includes components such as transformers, rectifiers, capacitors, and voltage regulators

• Shows the flow of electricity from the input source to the output load

• May include symbols for AC and DC power sources, ground connections, and voltage levels

• Common types include linear power suppli...read more

A superheterodyne receiver is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency.

• Superheterodyne receiver uses frequency mixing to convert incoming signals to a fixed intermediate frequency for easier processing.

• Bridge rectifier is a type of rectifier circuit that converts alternating current (AC) to direct current (DC) using four diodes arranged in a brid...read more
