Q1. What are half wave and full wave rectifiers
Ans. 
Half wave and full wave rectifiers convert AC to DC, differing in efficiency and output waveform.
• Half Wave Rectifier: Uses one diode, allows only one half of AC waveform.

• Example: Simple power supply for low-power devices.

• Full Wave Rectifier: Uses two or four diodes, utilizes both halves of AC waveform.

• Example: More efficient power supply for higher power devices.

• Half wave produces pulsating DC, while full wave produces

Q2. How can you filter a signal with ripples
Ans. 
Filtering signals with ripples involves using techniques to reduce unwanted oscillations while preserving desired signal characteristics.
• Use a low-pass filter to attenuate high-frequency ripples while allowing low-frequency signals to pass.

• Apply a moving average filter to smooth out rapid fluctuations in the signal.

• Consider using a Butterworth filter for a smooth frequency response with minimal ripples.

• Employ a Kalman ...read more

Ans. 
1 Tr of refrigeration is the amount of heat required to melt 1 ton of ice in 24 hours.
• 1 Tr of refrigeration is equal to 12,000 BTU/hr or 3.517 kilowatts.

• Newtonian fluids have constant viscosity, while non-Newtonian fluids have variable viscosity.

• Psychometric chart is a graphical representation of the thermodynamic properties of air-water mixtures.

• Entropy is a measure of the disorder or randomness in a system, while ent...read more
