Why is modulation necessary in signaling?
If you didn't have modulation it'd be the same signal going out the whole time, like a continuous tone - which can't really tell you that much. By modulating the signal you can say much more.
What is the passive nob on an amplifier?
The passive knob on an amplifier typically refers to a control that adjusts the signal without adding active amplification, often used for volume or tone adjustments. Unlike active components, passive knobs, such as potentiometers, modify the audio signal through resistance without boosting it, affecting the output levels or frequencies. This allows for fine-tuning the sound while maintaining the integrity of the original audio signal.
What is the carrier signal?
It is the pure sine wave signal with no modulation (data, information). It doesn't vary in amplitude or frequency. Not really a signal yet, which implies information. Call it a wave. From there, we have: CW- Morse code by turning the carrier on and off ICW- the I means interupted, close to the same as CW MCW- still coded but by Modulating the carrier with a tone. AM- the amplitude is modulated (by voice or tone) Basic voice- but creates sidebands FM- The frequency is modulated... SSB-Single sideband. Like AM but without the carrier and one sideband. Low bandwidth, low power. FSK- Frequency shift Keying, where the frequency of the modulation source is shifted hi to lo in ASCII, for teletype communication via radio links.. At this point a bit more complex....
How does the warble alarm siren works?
Basically, all that happens is an integrated circuit produces an output signal of 1010101010101010 over and over again. A second one processes it into a tone such as 1=1.8khz 0=2.6khz. This series of tones is then fed into a piezoelectric sounder.

The wavering tone warning signal alerts the fase of?
The wavering tone warning signal alerts the phase of an emergency or critical situation, indicating that immediate attention is required. This signal is commonly used in various contexts, including aviation, maritime, and public safety, to prompt individuals to take necessary precautions or actions. Its distinctive sound is designed to capture attention and convey urgency.
