The unipolar limb leads (aVR, aVL, aVF) are three of the standard leads used in an electrocardiogram (ECG) to record electrical activity of the heart from different angles. They provide information on the heart's electrical activity in the frontal plane of the body.
Unipolar NRZ (Non-Return-to-Zero) uses continuous voltage for the entire bit duration, while Unipolar RZ (Return-to-Zero) resets the voltage to zero halfway through the bit duration. This means that Unipolar RZ has more frequent voltage transitions compared to Unipolar NRZ in the time domain.
Biopolar multipolar unipolar
Sensory neurons are typically unipolar in structure. This means they have a single process, or neurite, that extends from the cell body and splits into two branches, one leading to the peripheral nervous system and one leading to the central nervous system.
A prosthetic limb or "prosthetic"
The "Tigger zone" in a unipolar neuron is the initial segment of the axon where action potentials are generated. Here, graded potentials from the dendrites accumulate and if they reach a certain threshold, an action potential is triggered.
I believe that a unipolar lead is one with a single lead while a bipolar lead is one with multiple or 2 or more leads.
standard or bipolar limb leads?
one limb electrode and a point midway between two other limb electrodes.
chest limb and augmented--------------------------------------------------------------------------------Standard Limb Leads (Bipolar) "Einthoven's Triangle"Lead I: right and left arms (lateral wall)Lead II: right arm and left foot (inferior wall)Lead III: left arm and [usually] foot (inferior wall)- Note that the right arm is always negatively charged and the left foot is always positively chargedAugmented Leads (Unipolar*)aVR: right arm (no specific view)aVL: left arm (lateral wall)aVF: left leg [usually foot] (inferior wall)Precordial "Chest" Leads (Unipolar*)- see link called "precordial 'chest' leads" in related links for diagramV1: 4th intercostal space to right of sternum (septal wall)V2: 4th intercostal space to left of sternum (septal wall)V3: between leads V2 and V4 (anterior wall)V4: 5th intercostal space at midclavicular line (anterior wall)V5: level with V4 at left anterior axillary line (lateral wall)V6: level with V5 at left midaxillary line, directly under midpoint of armpit (lateral wall)* It's important to note that with the unipolar leads, they work assuming that the "center point" is negative and the ends (the actual lead placement) are positive.
diode is unipolar
Unipolar NRZ (Non-Return-to-Zero) uses continuous voltage for the entire bit duration, while Unipolar RZ (Return-to-Zero) resets the voltage to zero halfway through the bit duration. This means that Unipolar RZ has more frequent voltage transitions compared to Unipolar NRZ in the time domain.
Uni- one. unipolar depression - this is form of depression without maniacal episode
Unipolar, multipolar and pseudo-unipolar
Poliomyelitis,is a viraly transmitted disease ,usually transmitted in contaminated water or food,which leads to paraysis of the limb or respiratory system,and often leads to death.
no. its unipolar
No.
Unipolar encoding lacks synchronization between senders and receivers Unipolar signals contain a direct current component that is unsuitable for certain media
