Q1:

Answer :

A PN junction diode is formed by joining P-type and N-type semiconductors. The P-type contains holes as majority carriers, while the N-type has electrons. At the junction, diffusion of carriers occurs, creating a depletion region with an electric field. When forward-biased, the electric field reduces, allowing

current to flow. In reverse bias, the field strengthens, preventing current flow except for a small leakage. PN junction diodes are significant for rectification, enabling AC-to-DC conversion in power supplies, and are foundational in devices like LEDs and photodiodes.

Q1:

Answer :

Analog signals are continuous and vary smoothly over time, representing real-world parameters like temperature or sound. Examples include audio signals in microphones and radio waves. Digital signals, on the other hand, are discrete, representing data in binary (0s and 1s).

Applications include computers, smartphones, and digital TVs. Analog signals are used in audio amplifiers, while digital signals dominate data transmission and processing.

Q1:

Answer :

Operational amplifiers are versatile components in electronics due to their high input impedance, low output impedance, and ability to amplify signals. Common applications include voltage amplifiers, integrators, differentiators, and filters.

Op-amps are essential in audio processing, instrumentation, and analog computing. Their use simplifies circuit design and enhances performance, making them indispensable in modern electronics.
