These speakers have a combined impedance of ________.

A Bluetooth signal can typically travel ________.

Speaker polarity can be tested using a small battery.

Which of these tools is used to test for a reading of infinity between the center antenna lead and the antenna?

The voice recognition system microphone is usually located near the glove box door.

100,000 ?F means ________.

Technician A says that crossovers are used to block certain frequencies to allow each type of speaker to perform its job better. Technician B says that a high-pass filter is used to block high-frequency sounds being sent to large woofer speakers, and a low-pass filter blocks low-frequency sounds being sent to tweeters. Who is right?

The satellite radio antenna can be mounted on a fiberglass or composite spoiler.

To safely install a power amplifier in-line capacitor, it must first be ________.

All of these can cause radio interference, EXCEPT ________.

Technician A says that FM requires an antenna whereas AM may be heard from a radio without an antenna. Technician B says that speakers reproduce the original sound and their impedance should be matched. Who is right?

More than one signal can be carried by a radio wave using a process called ________.

A bolt of lightning generates broad radio frequency bandwidths known as ________.

Technician A says that radios receive AM and FM signals that are broadcast through the air. Technician B says that the radio antenna is used to induce a very large voltage signal as an input into the radio from the electromagnetic energy from the broadcast station. Who is right?

The number of times a particular waveform repeats itself in a given amount of time (frequency) is measured in ________.

Which of these is a term used to describe when information is added to a constant frequency?
