ET ATT COMP TEST
AF Amplifier - ANS-- A volume controlled amplifier that raises the power stage of the audio
signal to a fee enough to power the loudspeaker of the receiver.
- Comprised of a Pre-Amp, Driver, and Push-Pull Amplifier.
Air-to-Air Cooling - ANS-- Air shifting beyond the heat-producing component absorbs the
heat and is pressured thru a heat exchanger with the aid of an inner blower
- Used in sealed enclosures
All magnets own: - ANS-A North Pole
A South Pole
Flux Lines
AM Receiver Pipeline - ANS-RF Input -> Tuner -> IF Amp -> Detector -> AF Amp -> Audio
Output
Arc Burns - ANS-Caused with the aid of excessive temperatures close to the body. Can be
because of arcs or explosions.
Burnishing Tool - ANS-Tool used to smooth relay contacts.
Common Base - ANS-- High voltage advantage(Assumed Av of 10).
- No phase shift.
Common Collector - ANS-- High cutting-edge gain, but low voltage benefit(Assumed Av of
1).
- No phase shift.
Common Emitter - ANS-- High electricity benefit.
- Assumed Amplification Value(Av) of 10.
- Most usually used for amplifiers.
- Has a one hundred eighty degree segment shift.
Coned and Cratered Contacts - ANS-The only form of relay damage that may occur while
contemporary flows in a single route.
Continuity - ANS-- The resistance of a twine/connection
- There are two readings for continuity, zero Ohms(short) or Infinite Ohms(open)
Continuous motor - ANS-- Motor wherein the shaft spins continuously
- Can be AC or DC
, Counterelectromotive Force (CEMF) - ANS-- The electromotive pressure (EMF) that is
brought on inside the armature generating a modern-day within the opposite route. The
precipitated EMF in a motor.
- Increases as rpm will increase
Crystal Oscillator - ANS-Use a crystal to determine oscillator frequency. Frequency must be
stated at the crystal(no math vital).
Cutoff - ANS-Point when base bias causes modern-day flow to stop. Happens when EB
Junction is reversed biased.
Detector - ANS-- Usually a made from diode(rectifier) with a few low bypass filters(RC
Circuit).
- Detects and extracts the audio intelligence from the IF amplifier and passes the output
audio to the AF Amplifier.
Different Current Amounts vs the Body: - ANS-1-five mA: Faint tingling to mild surprise
6-16 mA: Painful surprise, shaky muscle groups
17-ninety nine mA: Extreme pain, hard to permit cross, coronary heart flutters start
one hundred-2000 mA: Heart flutters precise, excessive muscle contractions, nerve damage,
tremendous chance of dying.
2000+ mA: Cardiac arrest, organ damage, extreme burns, certain demise.
Diode Bias Voltage - ANS-Diodes need a bias voltage to conduct
- Germanium diodes need 0.Three V
- Silicon diodes need zero.7 V
Driver - ANS-Amplifies audio signal current to drive push-pull amplifier.
Efficiency(Rotating Machinery) - ANS-- The score of how a motor modifications energy.
% Efficiency = (Pout/Pin) * 100
Electrical Burns - ANS-Most extreme type of burn, results from modern flowing thru
tissue/bone.
Ferrous Particles - ANS-Ferrous approach iron. A material with out ferrous debris is
NONMAGNETIC.
Fidelity - ANS-An amplifiers capacity to recreate an enter waveform. A magnificence-A
amplifier recreates the whole wave shape.
Filter(Power Supply) - ANS-Changes pulsating DC to Smooth DC.
Flux Lines - ANS-Lines that form a magnetic discipline across the magnet, shifting from
North to South outside the magnet.
Fuses - ANS-Open when an excessive amount of modern melts them.
