What does an AM FM tuner do?
Modern radio tuners use a superheterodyne receiver with tuning selected by adjustment of the frequency of a local oscillator. This system shifts the radio frequency of interest to a fixed frequency so that it can be tuned with fixed-frequency band-pass filter.

What is FM tuner sensitivity?
Among FM tuner specifications, sensitivity usually gets top billing. Sensitivity describes the tuner’s ability to pull in weak or distant stations – a critical factor if you live in the outer suburbs or in a rural region. The lower the number, the more sensitive the tuner.
Is AM or FM Better?
With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static.
How does FM tuner work?
The job of a tuner is to separate one sine wave from the thousands of radio signals that the antenna receives. Tuners work using a principle called resonance. That is, tuners resonate at, and amplify, one particular frequency and ignore all the other frequencies in the air.

How do I get good FM radio reception?
Get a new antenna. Switching from an indoor to an outdoor antenna can greatly improve FM reception. If you have a directional antenna, try switching to an omnidirectional antenna, or vice versa. Directional antennas can pick up stations from farther away, but omnidirectional antennas work well for closer stations.
Is AM radio going away?
On October 27, 2020, the FCC voted to allow AM stations to eliminate their analog transmissions and convert to all-digital operation, with the requirement that stations making the change had to continue to make programming available over “at least one free over-the-air digital programming stream that is comparable to
Why is DAB radio so bad?
Much worse – because it’s an older CODEC. Internet radio feeds will be using AAC or other more efficient CODECs. The only station which broadcasts on DAB with decent quality is Radio 3, and even that is -just- OK. Generally, assuming you’ve got internet coverage, you’re better off streaming than using DAB.
What is Rx sensitivity?
Rx sensitivity indicates the minimum amount of light required by the receiver to operate correctly.
What is the role of amplitude limiter in FM receiver?
In FM receiver, role of amplitude limiter is to amplify low frequency signals. Explanation: Amplitude Limiter circuit is used in FM receiver to remove the noise or any variation in amplitude present in the received signal.
How do I check the sensitivity of my receiver?
To calculate receiver sensitivity, we add the overall noise figure of the receiver to the noise floor. This quantifies the noise floor at the input to the demodulator. The signal must be higher than the noise floor by the carrier to noise ratio required for a desired signal quality.
