electronics is the control and manipulation of flow of electrons. There are two types of electronics: Analog and Digital
Analog has an infinite amounts of amplitude points (the Y axis). Analog due to its nature can produce a prefect sin wave
Digital only has two points; logic high and low typically valued at 5 and 0 volts respectfully, though the voltage value can be different. Since digital only has two states, bits of data must be grouped in order to produce amplitudes value
take in point a CD
to simplify we'll use a 5 bit sample rate
since this is binary based (0's and 1) we'll use the formula 2n (where is the number of bits) to figure out all the values that can be expressed (25=32 total values from 0-31)
16|8|4|2|1 base 2 notation
0|0|0|0|0 =0 (value of bits)

1|1|1|1|1 =31
This means that if a CD were to have a 5 bit sample rate, there is 31 voltage level points. If 10 bits per used then 1,024 voltages levels, etc. The more bits used per sample rate, the less choppy the wave sounds due to the voltage points (square wave even with high sampling cannot create a perfect sin wave). Since data is stored linear on a CD there is comprise between length time and sample rate
for this example a CD can hold 500MiB (Mega Bits) and can hold 70 minutes of music
500/70 = 7.1 MiB recorded per minute or a sample rate of 119 Khz
If the CD can store 90 minutes worth of music
500/90= 5.5 MiB recorded per minuter or a sample rate of 92.5 Khz
Sorry for the long post. Hope it helps you understand electronics Electronics is a branch of physics relating to electron emission and behavior. there are no two or three types of electronics only ONE. There many branches of applications with electronics and there not to be confused as types.
Actually, electron microscopes use a beam of electrons instead of light to produce a magnified image. This allows for much higher magnification and resolution compared to optical microscopes.
true
It uses electromagnets.
FESEM stands for Field Emission Scanning Electron Microscopy. It is a high-resolution imaging technique in electron microscopy that uses a field emission electron source to produce a fine electron beam for imaging the surface of a specimen at nanoscale resolution.
It uses a combination of lenses.
a transmission electron microscope uses electron beams rather than light.
Electron microscopes.
The electron microscope is a type of microscope that uses electrons to enlarge and illuminate an image of a specimen.
A Scanning Electron Microscope
A transmission electron microscope uses a beam of electrons to create detailed images of the internal structure of a sample, while a scanning electron microscope uses a focused beam of electrons to create high-resolution surface images of a sample.

The compound microscope is a light microscope that uses light to "see" microbes. Viruses are too small.The electron microscope uses electrons to "see" microbes or viruses.
the electron microscope is called that because it uses beams of electrons to accurately measure distances on atomic scales
That would be an electron microscope - the magnets are used to deflect the electron beam.That would be an electron microscope - the magnets are used to deflect the electron beam.That would be an electron microscope - the magnets are used to deflect the electron beam.That would be an electron microscope - the magnets are used to deflect the electron beam.
The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.
