Modulation is the process of varying a carrier signal's properties to transmit information efficiently.

• Modulation is used to transmit information over long distances.

• It allows multiple signals to be transmitted simultaneously without interference.

• Modulation helps in improving the signal quality and reducing noise.

• Different modulation techniques include amplitude modulation (AM), frequency modulation (FM), and phase mod...read more

The program counter is a register that keeps track of the next instruction to be executed in a computer program.

• The program counter is a special register in a computer's central processing unit (CPU).

• It holds the memory address of the next instruction to be executed.

• After each instruction is executed, the program counter is incremented to point to the next instruction.

• In case of conditional or unconditional jumps, the ...read more

A latch is level-sensitive and stores data as long as the enable signal is active, while a flip flop is edge-triggered and stores data only on the rising or falling edge of the clock signal.

• Latches are level-sensitive, while flip flops are edge-triggered.

• Latches store data as long as the enable signal is active, while flip flops store data only on the rising or falling edge of the clock signal.

• Latches are simpler and h...read more

Op-amp is an electronic device that amplifies the difference between two input voltages.

• Op-amp stands for operational amplifier.

• It has a high gain and can amplify signals.

• It has two input terminals, one inverting and one non-inverting.

• Op-amps are widely used in various applications such as amplifiers, filters, oscillators, and

There are no classes in C as it is a procedural programming language.

• C is a procedural programming language, not an object-oriented one.

• It does not have the concept of classes or objects.

• Instead, it uses functions and structures to organize code.

• Structures can be used to create user-defined data types.

• For example, a structure can be defined to represent a person with attributes like name, age, and address.
