The 8051 interrupts are INT0, INT1,TO ,T1 , TI/RI. All these interrupts are controlled by IE (interrupt enable) register.

A controller which controls the motor is called Variable Frequency Drive. By varying the frequency and voltage of supply it controls the motor

The main components of Phase Locked Loop are a phase detector with a voltage controlled oscillator. It also has loop filter feedback.

Whenever a signal is sampled below Nyquist rate (fs < 2B), the signal is called under sampled and the Aliasing effect hampers the results.

curve tracing- a picture speaks more clearly than words and numbers. A curve which is the image of functional relationship gives us a lot information about the relation.

The Circular Convolution can be performed using two basic methods which are concentric circle method and matrix multiplication method.

In order to make communication more safer and reliable digital signals are used. The basic digital modulation techniques are ASK, PSK,FSK and MSK

A matrix is the rectangular arrangement of arrays, that we arrange in rows and columns. the term “Matrix” was coined by James Joseph Sylvester in 1850. In this blog we are going to discuss about the matrix operations

CPU Scheduling is the process of determining which process will have exclusive use of the CPU while another is paused.

A race condition is an occurrence that can happen within a vital segment.

FD is a constraint in a database management system that specifies the relationship of one attribute to another attribute

The Entity-Relationship model (ER model) is a type of entity-relationship model.

A database architecture is a graphic illustration of the design of a database management system.

In the Greedy approach MST (Minimum Spanning Trees) is used to find the cost or the minimum path.

Piezometer is a instrument which measures the pore water pressure in a soil medium. It can be installed within structure of dam.

Arch dam is seen curved in plan with its convexity to the upstream side. It transfers the pressure towards the abutments by arch action.

Spillway is the passage provided for disposal of surplus flood water on the downstream side without affecting stability of water.

Weir is a crest wall constructed across a river to divert raise water of river into canal. Crest wall across a river raises the water.

Rivers are part of the surface water which flows from their source region to their mouth. The importance of river depend on length, width etc.

Cross Drainage work is constructed for crossing canal water safely over or under the drainage water.It should be avoided if possible.
