What are the applications of RC coupled amplifier?
They are widely used as voltage amplifiers (ie. In the initial stages of public address systems) because of their excellent audio-fidelity over a wide range of frequency. However because of poor impedance matching this type of coupling transistor circuits is rarely employed in final stages
Why is ce configuration employed in transistors?
for the same reason cs is employed with FETs and cc is employed with vacuum tubes: high voltage gain & high current gain.
What is Transistor Controlled Ignition?
Instead of using a distributor to determine when each cylinder fires, the car's ECU uses camshaft and crankshaft position sensors, along with MAP/MAF and throttle position sensors to determine the optimum time to fire each cylinder for the most power/lowest emissions. As opposed to fixed advance (vacuum or centrifugal) employed in distributors. Transistor Controlled Ignition is commonly referred to as Coil On Plug (COP), Transistor Controlled Ignition is just marketing bumpf to make it sound awesome.
Electromagnetic spectrum that Is commonly employed in land surveys?
Visible light
Name the substance which is commonly employed as a cooling agent in the refrigerator?
freon
Why is biasing needed?
The function of BiasingA BJT (Bipolar Junction Transistor) require a voltage normally in the range of 0.7V for the internal junctions to become conductive. It is a fixed parameter of Silicon (Si) due to the amount of 1.1eV required to get electrons from the valence energy band into a conductive band. To be able jump the energy gap which is a forbidden band for electrons or to raise the Fermi energy level in the atom. The energy, whether it is electrically applied, thermally or optically, is required to be able change the state of a semiconductor from an insulator to an conductor. You can read more on "semiconductor theory" for better understanding. Then with a non-linear relationship the conductivity will increase as one increase the forward bias current through the base to emitter junction. Biasing is used for classical transistor amplifier applications. Biasing is required to have the transistor half way saturated for Class-A amplification or barely switched on for Class-B power amplifiers. If a Class-B amplifier is not biased, then the lower 0.7V of the audio or sine wave will not be amplified causing crossover distortion. When you bias it correctly, the distortions will be gone, since the entire half wave will then fit into the on state of the transistor. If a Class-A amplifier is not correctly biased, premature clipping on the positive or negative part of the wave will occur.Biasing may be used for other applications as well, such as photo transistors, internal construction of IC's such as op-amps.

What is transistorized ignition?

What type of research method did freud commonly employ?
Hi everybody, Freud employed case studies and clinical observations.
What is commonly meant by the initials CEH?
CEH most commonly means Certified Ethical Hacker. It is a term used for people who are employed by organizations to test their cyber security and computer systems by "hacking" them.
What ensembles is the sitar most commonly employed?
Since the sitar was becoming very popular it was mostly played with a country band or a solo ensemble.
