Discrete Vs Analog I/O Signals Vs Digital Signal

         The first step of digitization is to sample the analog signal. Output of this process is a discrete time signal. At this point, there is no constraint on amplitude of the output signal. Figure below shows both the signals.   ...

What are Static Variables and functions in C ?

In C, functions are global by default. The “static” keyword before a function name makes it static.Unlike global functions in C, access to static functions is restricted to the file where they are declared. Therefore, when we want to restrict access to functions, we make...

Difference between float and double in C/C+

Double has 2x more precision then float.float is a 32 bit IEEE 754 single precision Floating Point Number1 bit for the sign, (8 bits for the exponent, and 23* for the value), i.e. float has 7 decimal digits of precision.Double is a 64 bit IEEE 754 double precision Floating...

Difference between Definition and Declaration ?

 Declaration of a variable is for informing to the compiler the following information: name of the variable, type of value it holds and the initial value if any it takes. i.e., declaration gives details about the properties of a variable. Whereas, Definition of a variable...

How can I calculate the resolution of load cell?

 Let's assume that you have 5kg loadcell. Its output is specified for 1mV/V excitation meaning that if you have 5V excitation, you shall get 5mV output for a full-scale load of 5kgs.Simply correlate this as 5000uV (microvolts) corresponding to 2000gm of load.Next,...

What is Common-mode Voltage Gain ?

Common-mode voltage gain refers to the amplification given to signals that appear on both inputs relative to the common (typically ground).You will recall from a previous discussion that a differential amplifier is designed to amplify the difference between the two voltages...

What Is Static Code Analysis?

Static code analysis is a method of debugging by examining source code before a program is run. It’s done by analyzing a set of code against a set (or multiple sets) of coding rules. Static code analysis and static analysis are often used interchangeably, along with...

WOW ! FRAMs as alternatives to flash memory in embedded designs

 Ferroelectric random access memory (FRAM) is widely known as a non-volatile, stand-alone memory technology that has been a part of the semiconductor industry for more than a decade.In recent years, integrated circuit manufacturers have been considering FRAM as a strong...

What is Proof of concept POC ?

     A Proof of Concept (POC) is a small exercise to test the design idea or assumption. The main purpose of developing a POC is to demonstrate the functionality and to verify a certain concept or theory that can be achieved in development. Prototyping...

What are the difference between C and Objective C ?

    The language C was developed in early 1970s by Dennis Ritchie for the UNIX Operating system. It a general purpose, procedural programming language. The language is used for developing system applications as well as desktop applications.    Objective...

What are Procedural and Object Oriented Programming ?

Procedural Programming:Procedural Programming can be defined as a programming model which is derived from structured programming, based upon the concept of calling procedure. Procedures, also known as routines, subroutines or functions, simply consist of a series of computational...

What is Scavenging in Two-Stroke Engines ?

     The process of simultaneously purging exhaust gas and filling the cylinder with fresh charge for a new cycle is referred to as scavenging.     The main scavenging methods are Cross scavenging,  Loop scavenging...

What actually inside your Car Steering?

 The chances are your car has Rack and pinion steering. It’s been an incredibly popular engineering choice for years, but have you ever stopped to ponder exactly how it works?Thankfully, the basics aren’t hard to grasp at all: it’s all about turning rotational motion...

Low Voltage Vs High Voltage Programming

There are two modes for programming a PIC® Microcontroller, High Voltage (HV) mode, and Low Voltage (LV) mode. The Low-Voltage Programming (LVP) mode allows the PIC Flash MCUs to be programmed using the operating voltage VDD of the device. This offers many advantages to...

Types of States in Digital Output

 A three-state, or Tri-State, output has three electrical states: One, zero, and "Hi-Z," or "open." The hi-Z state is a high-impedance state in which the output is disconnected, leaving the signal open, to be driven by another device (or to be pulled up or down by...

Know the difference : Sensitivity Vs Resolution

 Resolution is the smallest reading difference that is possible in a given measuring instrument. For example, take a scale, also known as ruler, one can see that 1 mm (or 0.1 cm) is the resolution of the measuring scale. For example, I measure the length and width...

What are the different Mounting Positions of Electrical Motors ?

    Proper motor installation and mounting position is essential in obtaining top-quality operation, efficient performance, and maximum reliability.Here are the different type of common mounting positions as follo...
