Band-pass filter

needed. Considering the ubiquity of power lines, it implies that with PLC, virtually all line-powered devices can be controlled or monitored. Generally, PLC uses the same electric cables for the purpose of power delivery and communication. A high-pass filter, called a coupling interface is used in separating the powering and signaling circuits. This coupling interface makes the connecting different circuits with different voltage levels possible. The communication signal is fed…

ears that function in many ways, specifically in the detection of vibrations and seismic cues due to their ear structure that have three essential parts: the outer ear which captures sounds, a middle ear which filters and amplifies sound, and the cochlea (the inner ear) which is a band-pass filter and transducer of sound into neural impulses (Ketten 1994). Another important functional aspect of the middle ear is that the quantity of sound energy captured by the pinnae and tympanic membrane…

All heartbeats consist of a mechanical component and an electrical component. The heartbeat is created by cardiac depolarization caused by electrical currents that induce muscle contraction. The electrical component of the heartbeat begins in the Sinoatrial (SA) Node and its function is to send electrical impulses that stimulate your heart to beat, and these impulses induce the atria to contract. As the atria contract, the impulse moves on to the Atrioventricular (AV) node which leads the…

PCR History The invaluable molecular technique known as PCR, or the polymerase chain reaction, was discovered by a biochemist named Kary Mullis. Mullis was doing research in the early 1980s at a biotechnology company in California when he initially thought of the idea regarding PCR. PCR was developed by a combination of several techniques already in existence; the synthesis of oligonucleotides and their utilization to synthesize new copies of DNA that were specific using DNA polymerases. Mullis…

attempting to traverse a more elevated position in a vain attempt to procure a quarter of a rundlet of a hydrogen and oxygen compound. Half their number experienced an uncontrollable descent that resulted in severe damage to his pate. And soon it came to pass that the rest of the labor force followed suit, but with far less serious consequences. You probably did not understand the paragraph I just read, but it was the nursery rhyme of Jack and…

function which enables the mind to filter out stimuli that are irrelevant to the task/process that is being performed or to the current state of the mind (MacLeod, Colin, 2007). In psychology, it refers to the ability to constraint or curtails certain behaviours, especially impulses and desires consciously or unconsciously. In the real life, it prevents us from acting impulsively such as physically retaliating against someone who insulted us and to adjust a pass in football due to the defender…

F214 Communication, Homeostasis and Energy Module 2 Excretion 4.2.1 Excretion a. Define the term excretion Excretion-The removal of metabolic waste from the body which are by products or unwanted substances from cell processes. b. Explain the importance of removing metabolic wastes, including carbon dioxide and nitrogenous waste from the body Carbon dioxide Excess carbon dioxide is toxic and has three main effects: The majority of carbon dioxide is carried in the blood as…

The Animal Book Chapter 1: Animal characteristics Chapter 2: Body Parts Body plans refer to similarities in development, structure, and function among members of a particular group (phylum). At some point, members of that group share the same body plan during their development process. Which could be a possible explanation for shared structural plans that have been observed in the anatomy and embryology. Timing, pattern, and scale of development determine the organism's shape, and closely…
