741 ic AM radio 📻 (Full details.)
Ғылым және технология
AM radio, or Amplitude Modulation radio, is a broadcasting technology that modulates the amplitude of radio waves to carry audio information. In simple terms, it works by varying the strength of the radio signal to encode sound. The transmitter sends a carrier wave at a constant frequency, and the audio signal is superimposed by changing the amplitude of the carrier wave. The receiver then demodulates the signal to retrieve the original audio content, allowing you to hear broadcasts on AM frequencies.
The main difference between AM (Amplitude Modulation) and FM (Frequency Modulation) radio lies in how they encode audio signals onto radio waves:
1. *Modulation Method:*
- AM modulates the amplitude of the carrier wave.
- FM modulates the frequency of the carrier wave.
2. *Signal Quality:*
- AM signals are more susceptible to interference, such as static and atmospheric disturbances.
- FM signals provide better sound quality and are less prone to interference.
3. *Coverage and Range:*
- AM signals can travel longer distances and penetrate obstacles better, making them suitable for long-range broadcasting.
- FM signals have a shorter range and are more affected by obstacles, but they offer higher fidelity within their coverage area.
4. *Bandwidth:*
- AM radio uses a smaller bandwidth compared to FM radio.
5. *Frequency Range:*
- AM radio typically operates in the medium-frequency (MF) band.
- FM radio operates in the very-high-frequency (VHF) band.
In summary, while AM radio is known for its longer range and ability to penetrate obstacles, FM radio provides better sound quality and is less susceptible to interference. The choice between them often depends on the specific requirements of the broadcasting situation.

Bro You are Very Talented and Knowledgeable! But thodi si n Video Quality+Editing bhut achhe level pr le jao..Tab apka channel Growth 📈(*THUMBNAIL REAL BUT VERY ATTRACTIVE )bhot teji se karega just like add some transition and background ma koi scal table or koi bhi achhi chije lga kr..! Its only a small suggestion bro..all the best

Frist comment
Very good video. Are you bangali
❤❤
Please links pin kar do please 🙏
Hello bro where can we buy all components required or From where do you buy all components for your projects. Please reply 🙏🏿
Bhaiya aap Electronic ka full course bnaea
Bhai please make it with lm386ic as I do not have 741operational amplifier
Comment section me pin kr diy kro
Vai mujhe vi thora electronics ki all partas ki bare me kuch sikha sakte ho
Konse College se Engineering ke hai bhai 🤔 Aur Exact konsi Branch?
Bhai best video hai par noise Kam kar ne ke liye kya karna hoga ❤

Variable capacitor Ko ghumana hoga, noise nahi hai ismein, Jo kuchh bhi sunai de raha hai vah video banane ke waqt microphone ki vajah se a raha hai.
Bro ya sab aap na kaha sa shika marko bhi shikna ha please batao bhai marko bhi electronic ma intrest ha or ma na 12 pass kar li ha aap batay kai ma ab kaya karu
Bhaiya sabhi products ka nam likh diya kro
Aap banagali ho?
dada 10nf capacitor ke badle 103pf capacitor chalega kya ????
