What else can I help you with?
What percentage of central frequency as bandpass for a narrow band amplifier?
central freqency of narrow band pass filter is the measure of difference between upper and lower cut off freqency
What is bifference between optical bandgap and semiconduct0r bandgap?
we all know that electrons,photons, phonons can excite an electron from valence band to conduction band...i think the main difference between electronic bandgap and optical bandgap is that in electonic its the energy required for an electron to move from the valence band to the conduction band.but in optical bandgap photons(packet of energy in the form of light waves) are assisting the electrons to move from valence band to conduction band.The difference between optical and electronic bandgap is more complexe actually. The optical bandgap is the one that can be measured using optical techniques (based on transmission and reflection, i.e. Tauc plot). However, this measurement does not take into account all traps you might have within the bandgap that can modify the energy required to move one charge carrier from the conduction band ans the conduction band. The electronic band gap (which is the one of interest in fine, in an integrated device) is measured under operation. Thus, for many devices (lasers, solar cells...etc.) the electronic bandgap (energy required to get the device working) can defer from the optical bandgap.
What is the difference between the resistance of conductor and insulator?
Conductors allow most, if not all, electricity to pass through it. This is due to "wandering electrons" that aren't tightly bound to the nucleus of the conductor itself.Resistors conduct some, but not all electricity to pass. It somewhat resists it, hence resistors.Insulators do not allow electricity to pass through it due to the electrons being so tightly bound to the nucleus.
Differentiate in between conductor and semiconductor and insulators using band diagram?
Conductor-one which conducts(allow current)electric city in all condition. Semiconductor-One which behaves like conductor as well as insulator depending on condition. Insulator-one which donot conduct(allow current)electric city in all condition
What different between band gap silicon amorphous with crystaline?
Amorphous Silicon (a-Si) has band gap of about 1.7eV, whereas crystalline (c-Si) only has a band gap of 1.1eV
What are the disadvantages of outband signalling over inband signalling?
disadvantage of in-band signalling
What is signal?
In telephony, signaling is the exchange of information between involved points in the network that sets up, controls, and terminates each telephone call. In in-band signaling , the signaling is on the same channel as the telephone call. In out-of-band signaling , signaling is on separate channels dedicated for the purpose.
What is the difference between chain printer and band printer?
The difference between a chain printer and a band printer is a chain printer has a chain that the characters are on and a band printer has a band for the characters.
What is the difference between gastric band and lap band surgery?
The difference between gastric band surgery and lap band surgery is the type of procedure which is undertaken and the complications which may arise from the surgery.
What is the difference between a band with a guitar and a band without a guitar?
The guitar.
What is the difference between frequency diversity and space diversity?
What is the Diffeence between the In band and Out of Band Frequency Diversity
Which signaling method carries tones in the same voice frequency and circuit of a telephone call?
in-band signaling
What type of signaling transmits call setup on the same channel as a voice signal?
In-Band Signaling (IBS)
What is the difference between rock band and rock band 2?
I think the only difference is the music list....and the big number 2 on the box :)
What is the difference between an bandage and a band aid?
A band-aid is the brand name, while a bandage is what its really called.
What is the difference between ABBA and the beetles?
The beetles were a boy band
What is the difference between rock band and guitarhero world tour?
I don't see a big difference.
