Basics of electronics(Gates, MOSFET, Opamps), reasoning
A half wave rectifier is a simple electronic circuit that converts AC voltage to pulsating DC voltage.
Consists of a diode connected in series with a load resistor
Allows only the positive half cycle of the input AC signal to pass through
Output voltage is the same as the input voltage during the positive half cycle
CMOS functions by using both NMOS and PMOS transistors to create logic gates and memory cells.
CMOS stands for Complementary Metal-Oxide-Semiconductor
It uses both NMOS (n-type) and PMOS (p-type) transistors to create logic gates and memory cells
CMOS technology is widely used in digital integrated circuits due to its low power consumption and high noise immunity

Calls from cell phone A to cell phone B are made through a cellular network using radio waves.
Cell phone A initiates the call by sending a signal to the nearest cell tower.
The cell tower relays the signal to the mobile switching center (MSC).
The MSC connects the call to the appropriate cell tower near cell phone B.
Cell phone B receives the call signal and establishes a connection with cell phone A.

There are two types of optical fiber: single-mode and multi-mode. The head office under me works in New York.
There are two types of optical fiber: single-mode and multi-mode.
Single-mode fiber is used for long-distance communication, while multi-mode fiber is used for shorter distances.

The number of tubes in a 48 fibre cable varies depending on the specific cable design.
The number of tubes can range from 4 to 12 in a 48 fibre cable.
Each tube can contain multiple fibers, typically 4 to 12 fibers per tube.
The specific cable manufacturer and design will determine the number of tubes in a 48 fibre cable.
For example, a 48 fibre cable may have 6 tubes with 8 fibers in each tube.
The depth of normal ducting refers to the measurement of the vertical distance from the top of the duct to the bottom.
The depth of normal ducting can vary depending on the specific application and requirements.
In residential HVAC systems, the depth of ducting is typically around 8-12 inches.
In commercial or industrial settings, the depth of ducting can be much larger, ranging from several feet to even multiple stories.

The question is asking for the codes of all colors.
Colors have specific codes assigned to them.
These codes are used in various industries like printing, web design, and manufacturing.
For example, the color code for red is #FF0000 and for blue is #0000FF.

M20 grade is a type of concrete mix used in construction, with a compressive strength of 20 megapascals (MPa).
M20 grade refers to the mix ratio of cement, sand, and aggregate used in concrete.
It is commonly used for general construction purposes.
The compressive strength of M20 grade concrete is 20 MPa after 28 days of curing.
The mix ratio for M20 grade is 1:1.5:3, which means 1 part cement, 1.5 parts sand, and 3 parts
The torque value of an M30 bolt depends on various factors such as material, lubrication, and application.
The torque value can range from 1500 Nm to 4000 Nm depending on the factors mentioned above.
It is important to consult the manufacturer's specifications or a torque chart for the specific bolt and application.
Using the correct torque value is crucial for ensuring the safety and integrity of the bolted joint.

Admixture is a material added to concrete to modify its properties.
Admixtures can improve workability, strength, durability, and reduce water content.
Examples of admixtures include water reducers, accelerators, retarders, and air-entraining agents.
Admixtures can also be used to reduce the carbon footprint of concrete.
Admixtures are typically added to the concrete mix during batching.
