What is radio AM?
AM - Amplitude Modulation FM - Frequency Modulation AM radio is simply lower frequency sound waves caused from the transmitter. This can cause the sound to become very soft or loud at stages. Static sound can also me heard from house hold appliances interfering with the Radio. The quality of the Radio can be heard less better than FM.
Does visible light have a higher frequency than gamma rays?
No, visible light has a lower frequency than gamma rays. Gamma rays are the highest frequency of electromagnetic energy. They are above X-rays.
Do am radio waves have a lower frequency then ultra violet radiation?
Radio waves and ultraviolet waves are the same physical phenomenon.The difference is that radio waves have a much greater wavelength.(That's equivalent to saying that they have a much lower frequency.)
How did Edwin Armstrong invent the FM radio?
Edwin Armstrong invented FM radio in the 1930s by developing frequency modulation as a method to improve audio quality over AM radio. He discovered that varying the frequency of the carrier wave, rather than its amplitude, reduced noise and static interference, producing clearer sound. His work involved extensive experimentation and the creation of the first FM transmitter and receiver. Armstrong's innovations laid the foundation for modern FM broadcasting and significantly advanced radio technology.
What are the frequency limits for carrier signals used by other AM stations in that area?
No higher than 1090 kHz and no lower than 1110 kHz
What is a duplexer?
A duplexer is a device that allows bi-directional (duplex) communication over a single channel. In radar systems, a device that isolates the receiver from the transmitter while permitting them to share a common antenna. Note 1: A duplexer must be designed for operation in the frequency band used by the receiver and transmitter, and must be capable of handling the output power of the transmitter. Note 2: A duplexer must provide adequate rejection of transmitter noise occurring at the receive frequency, and must be designed to operate at, or less than, the frequency separation between the transmitter and receiver. Note 3: A duplexer must provide sufficient isolation to prevent receiver desensitization.Braimah prosper
Why battery life of a pager is better than a cellphone?
Because a pager is just a radio receiver and not a radio transmitter. A cell phone is both a receiver and a transmitter. A receiver uses much less battery power than a transmitter does. And because a pager's disposable alkaline battery holds more power than a cell phone's rechargeable battery.
How do you create transmitter?
we can create transmitter by using modulator circuit depending what frequency range you would like to use if you want to use FM range 88 to 108 MHz than you may refer to FM modulators and if you are going to more than 300MHz than you will need RF receiver.
What is meant by repeaters in radio wave propagation?
Radio Masts an SatellitesThe frequencies in the high part of the spectrum from the VHF band and higher can only work line of sight, so the receiver have to see the antenna of the transmitter whatever the power of the transmitter, not like with shortwave where you can transmit around the world as long as you have enough power. Repeaters is usually erected on high sites, it is a receiver tuned to the original transmitters frequency on the other end a transmitter tuned slightly offbeat in other words a bit lower or higher frequency than it's receiver from where any receiver that is in sight can receive the signal.Al the radio masts that is some times visible on mountains and hills are repeaters, the radio ham leagues in most countries have there own network of repeater that is used in the two meter band and higher, repeaters can not be erected on the ocean, so that is what satellites are for.
Can a tv be hacked into a transmitter rather than a receiver?
yes . electronically it is possible to convert a tv reciver into a crude very low power transmitter. however if one has the knowledge to do the conversion, it will be far more simpler to attach a transmitter device to the video player or camera rather than using a small section of the TV set as a transmitter
Is the frequency of blue light higher or lower than violet light?
Blue light has a lower frequency than violet light. Violet light has the highest frequency in the visible spectrum, while blue light has a slightly lower frequency than violet light but higher than green light.
Will the Sony Receiver 1992 compare with a lower end Denon Receiver?
The Sony Receiver 1992 isconsiderably better than any low end Denon Receiver.
Which band of the electromagnetic spectrum has a frequency lower than microwaves?
Radio waves have a lower frequency than microwaves in the electromagnetic spectrum. They have the lowest frequency and longest wavelengths of all the electromagnetic waves.
What does Infrared waves have lower frequency than?
Mill
Does the color red have a lower frequency than the color green?
No, the color red has a longer wavelength and lower frequency than the color green. In the visible light spectrum, red light has a frequency of approximately 430–480 THz while green light has a frequency of approximately 530–580 THz.
Does red light have a higher frequency than green light?
No, red light is lower frequency than green light.
What sounds have a lower frequency than 20hz?
Sounds with a lower frequency than 20 Hz are infrasound, which include natural occurrences like earthquakes and some animal calls. These low-frequency sounds are typically felt more than heard.
