It may also include many typical communication system components or'blocks'such as amplifiers, equalizers provided they are also operating under linear and defined conditions.
22.
A "'rack case "'is a transit case with provision for mounting rackmount equipment such as amplifiers, computers, displays, radios, encryption devices, and so forth.
23.
The resulting sound pressure level depends on the sensitivity of the loudspeaker and the size and acoustics of the room as well as amplifier power output.
24.
The limiter acts as a class-A amplifier at lower amplitudes; at higher amplitudes it becomes a saturated amplifier which clips off the peaks and limits the amplitude.
25.
The usual test for microphonism in electron tubes is to tap the tube with a finger, light mallet, or small rubber ball while working as amplifier or oscillator.
26.
The effect of this is that class A amplifiers perform extremely well with music that has a low average level ( with negligible distortion ) with momentary peaks.
27.
This compares with a class-A amplifier which has efficiency of 25 % if directly driving the load and no more than 50 % for a transformer coupled output.
28.
This allows BJTs to be used as amplifiers or switches, giving them wide applicability in electronic equipment, including computers, televisions, mobile phones, audio amplifiers, industrial control, and radio transmitters.
29.
However, CFAs are available with gain-bandwidth products more than an octave higher than their VFA cousins and are also capable of operating as amplifiers very near their gain-bandwidth products.
30.
Bowls are often created next to rock faces, banks, or tree trunks to help reflect sound-the bowls themselves function as amplifiers to enhance the projection of the males'booming mating calls.
