OEE stands for Overall Equipment Effectiveness, a metric used to measure the efficiency of manufacturing processes.

• OEE takes into account three factors: availability, performance, and quality.

• It is calculated by multiplying availability, performance, and quality percentages.

• OEE helps identify areas for improvement in production processes.

• For example, if a machine has an availability of 90%, performance of 80%, and qual

AC-DC converter converts alternating current (AC) to direct current (DC) for various applications.

• AC voltage is converted to DC voltage using rectifiers

• Rectifiers can be half-wave, full-wave, or bridge rectifiers

• Filtering is done to smooth out the output voltage

• Examples include power supplies for electronic devices and battery chargers

Mixed signal design process involves integrating analog and digital components on the same chip.

• Mixed signal design combines analog and digital circuits on the same chip.

• Careful consideration of noise, power consumption, and signal integrity is crucial.

• Simulation tools like SPICE are used to verify the design before fabrication.

• Mixed signal design requires expertise in both analog and digital design techniques.

Expected CTC and take home should be based on industry standards and the candidate's experience and skills.

• Expected CTC should be in line with industry standards for the position and the candidate's experience level.

• Take home pay should be calculated after deductions like taxes and insurance.

• Candidates can research average salaries for similar roles in the industry to get an idea of what to expect.

• Negotiation is common...read more

Design a counter using flip-flops to count up or down based on the input signal.

• Use D flip-flops to store the count value

• Connect the output of one flip-flop to the input of the next flip-flop to create a ripple effect

• Use additional logic gates to control the direction of counting (up or down)

• Implement a reset signal to initialize the counter to a specific value
