Audio Analyzer/ BER

​ (a)   are multifunctional equipment used in audio frequency amplifier measurements.

This type of test equipment usually contains circuitry for an AC electronic voltmeter, a dual frequency audio oscillator, a wattmeter, and either a harmonic or intermodulation distortion filter.

• Audio analyzers
• Voltage meter
• Audio Amplifier
• Bit error rate test kit

One of the advantages of an audio analyzer is..

• The ability to detect and identify noise sources.

• The ability to measure the frequency response of a system.

• The reduction in the

  number of test leads required to monitor and check an amplifier.

• The ability to measure the power output of a system.

Audio

analyzers measure the accuracy of what?

• The speed of a computer processor

• An electronic circuit at reproducing a wave and can be used to

  test the noise through a receiver.

• The amount of data stored in a memory chip

• The clarity of a microphone

​ (a)   is a measure of telecommunication signal integrity

based on the quantity or percentage of transmitted bits that are received

incorrectly.

• Bit Error Rate
• Audio Analyzers
• Beta Tester
• Ohm Reader

Bit error rate is an __ indicator of full end-to-end

performance because it encompasses the receiver and transmitter as well

as the media between them.

• Effective

• Ineffective

• Reliable

• transparent

If errors are introduced into the data,

then the integrity of the system may be compromised. As a result, it is

necessary to assess the performance of the system, and bit error rate

testing (BERT) provides what?

• An ideal way in which this can be achieved.

• X,Y&Z

• BPSK

• A cost-effective way to identify problems.

True or False, Bit error rate testing (BERT) can be used over wired (e.g. Ethernet, fiber optic, etc.) and wireless

(e.g. cellular) networks, or any other system used to transmit data.

• True

• False

How is BER calculated?

• By measuring the distance between the two radios

• By comparing the number of correct bits to half the total number of bits sent.

• By counting the number of incorrect bits for a selected duration of time

• By dividing the quantity of bits received in error by the total number

  of bits transmitted within the same time period.
