An echocardiogram gives a visual picture of the heart muscle and chambers.
An electrocardiogram (EKG) produces a graph showing the electrical impulses of the heart's contractions. It shows various wave forms of the electrical strength and pattern.
The waveform for an electrocardiogram is the measurement of the heart beat. The waveform of an electromyogram is the measurement of the response of muscles.
difference between detector and diode
what is the difference between miniature circuit breaker and fuse
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
What the difference between envelop and coherent detection of AM signals
There is no potential difference between identical charges
An electromyogram measures muscle conductivity. An electromyelogram measures nerve conductivity.
The polarity at which it limits a waveform.
The output waveform will be limited to the difference between the supply and ground (or between the positive and negative supplies). This causes distortion of the output waveform.
biphasic have lower waveform compared to monophasic
simple waveform - something like a sine wave. Very pure sound like you used to get on the tv when that girl was sitting with the toys in the middle of the night. Complex waveform is like speech etc
Two locations are said to be "in phase" when the waveform is "lined up" so there is no voltage difference between the two points.They are out of phase if there is a voltage difference between them.If you are looking at an oscillograph reading of both, if they are in phase the waveforms will be identical magnitude at the same time. If out of phase, one will be shifted relative to the other causing a voltage difference.
wavelength
Because power dissipated in rl circuit is given by p= 1/2(LiΒ²)+ iΒ²R which will give a curve and not a linear graph. Secondly the graph is a cosine curve ,with a phase difference between current and voltage. Hence the waveform is not symmetrical to x-axis .
A Fourier series is a set of harmonics at frequencies f, 2f, 3f etc. that represents a repetitive function of time that has a period of 1/f. A Fourier transform is a continuous linear function. The spectrum of a signal is the Fourier transform of its waveform. The waveform and spectrum are a Fourier transform pair.
A continuous wave or continuous waveform(CW) is an electromagnetic wave of constant amplitude and frequencywave train:a series of waves travelling in the same direction and spaced at regular intervals ...
A class "A" amplifier amplifies the entire waveform, a class "B" amplifier only amplifies the first 1/2 of the wave form. See the images in the related link.
Not sure about duty cycle of a waveform. The frrequency is the inverse of the period and the period is the inverse of the frequency. Frequency (it pains me to tell you) is measured in Hertz, cycles per second. Period is the time for one cycle or seconds per cycle. If we let f be frequency and T be period, then f=1/T and T= 1/f
