GPS stands for Global Positioning System which was initially created for military usage. The first fully functional GPS was in 1995 in the US and was then included in vehicles in 1996. It is nothing but a group of satellites that revolves around the earth and recursively send messages to the earth's surface which are received by various devices to calculate the optimized location of the receiving device, this calculation requires information from at least 4 satellites which includes the coordinate positions and clock deviations. This is known as space technology. It is implemented everywhere on the earth without 100% ... Read More

Bluetooth is a technology that wirelessly connects with other systems using the radio frequency that uses 2.4 GHz frequency. Bluetooth is accessible up to 10 meters for sharing documents, media, photos, and videos. It avoids the usage of wires making it a wireless technology. It provides a secured data transmission, so the device needs to be paired before any transmission of data. Though a secure connection, the distance for transmission is less compared to today’s emerging technology. Bluetooth divides the data into packets and transmits it through the channels which use frequency hopping spread spectrum. Bluetooth Modes Bluetooth Connection Bluetooth ... Read More

Radio Transmission Radio waves are useful for transmitting data over long distances through air medium as it uses radio signals for transmission. Radio waves are broadcasted with Amplitude Modulation and Frequency Modulation schemes which use antennas. To travel long distances, AM radio signals use the lower carrier in frequencies which is higher than FM broadcasting but lacks sound quality at the receiver end whereas AM signals have better bandwidth which produces good sound quality and supports stereo signals during transmission. The radio waves used during transmission are omnidirectional, so signals can be propagated through all directions which provides a higher ... Read More

Two different and adaptable communication advancements that have been widely used in the past are Code Division Multiple Access (CDMA) and General Packet Radio Service (GPRS). A computerized cellular system called CDMA may use spread-spectrum techniques for flag transmission, whereas GPRS may use packet switching to enable mobile information interchange across cellular networks. In this article, we'll examine the fundamental differences between CDMA and GPRS, including their innovation, speed, network architecture, and security features. You may choose the innovation that is most suited for your portable communication needs by knowing these comparisons. What is CDMA? A CDMA (Code Division Multiple ... Read More

Magnitude and amplitude are frequently used interchangeably to describe characteristics of numbers in common parlance. Both words are interchangeable, according to a thesaurus. Yet in engineering, they signify two distinct things, therefore it's crucial to know the difference. The maximum positive or negative value to which a variable deviates from its mean is referred to as its amplitude. It is just the farthest a vibration or oscillation may go from its stable location (zero level). Because of this, signal amplitudes can either be positive or negative. On the other hand, a variable's magnitude is a measurement of how much its ... Read More

What is a JK Flip-Flop? JK flip flop is also a 1-bit storage device having two inputs similar to SR flip flop, but it has inputs denoted by J and K instead of S and R. It has two outputs viz. Q (normal output) and Q' (inverted output). The clock signal is used for synchronization of the circuit. The block diagram of the JK flip flop is shown in Figure-1 below. The operation of the JK flip flop can be understood with the help of its truth table which is given below − Inputs Output ... Read More

A system of components that is used to provide the desired response by controlling different parameters in the process is referred to as a control system. In a control system, the final output or response of the system is controlled by varying the input, and hence it named so. Based on the control mechanism used, the control systems can be classified into the two types namely, feedback control system and feed forward control system. The fundamental difference between the feedback control system and feed forward control system is that in the case of feedback control system, the corrective action is ... Read More

In the world of communication, there are two types of data that we encounter frequently, noise, and signal. These two terms are often used interchangeably, but they are not the same. Noise refers to any unwanted or random interference that occurs in a signal, while a signal is the desired information being transmitted. In this essay, we will discuss the differences between noise and signal in detail. What is Noise? Noise is described as any unwanted sound that is judged as overly loud and disruptive to hear. From a physics point of view, noise is regarded as indistinguishable from the ... Read More

In telecommunication systems, pulse and tone are two different kinds of signals. Tone signals are analogue signals represented by a continuous waveform, whereas pulse signals are digital signals represented by a sequence of on/off pulses or voltage levels. Read this article to find out more about Pulse and Tone and how they are different from each other. What is Pulse Dialing? In telecommunications systems, pulse refers to a way of signal transmission that involves sending electrical pulses down the telephone line. This method, also known as pulse dialing, is widely used in older systems for dialing telephone numbers. In pulse ... Read More
