Thank you sir for making this types of video
Sir your explanation is mind blowing. teaching manner is very simple that I can understand soon. Thank you so much sir
Very useful.... As it was all in one and comparitive... 😇👍
Awesome information sir...
Now I'm preparing for my seminar competition and you're video such a help for me....thanking you.
Best ever for me this TH-cam channel tq soo much sir for creating us such a wonderful nd complete knowledgeable video..I dnt know how I can said tqq to u..🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗😝😝😛
Hi mr. niket shah
Your video is just superb. Sir can you pls make a video on full details about substation switchgear ..
will try
Sir yes it's very very useful video. Your voice too good.
you are great sir i am student in 4th semester sir applied electronics ka total video kaise mile ga sir plz tell me know
Very well explanation sir.
👌👌👌....
I am your big fan sir....
Sir make a video about how AC frequency is generated in electric power station
Best channel for technical geeks
D does not stand for digital
Although making a signal by rapidly switching transistors on and off resembles digital processing that uses zeros and ones, Class D amplifiers are not digital devices. Some of them might have digital control circuits, but the amplifier circuits will be strictly analog
Which class of amplifier is best for gym 3000sft hall
Sir isi tarah ka vidio send karte rahiye ga
अब तक की सवसे अच्छी जानकारी है
Ap examples good daty ho plz Hz khz MHz ki b information dain.
Very helpful sir thanks Tarika bhuat acha he apka pdane ka 🙏

Kaun sa class ka amplifier sound best Hota Hai, sunane Mein Achcha lagta hai ? matlab sweet sonud Hota Hai?
Sir,Harmonic distortion kya hota ?
Mujhe bhut accha laga
Sir make a videos on electrical interview questions.
Thanks sir mast video 😊😊😊😊😊😊🙋
Please explain in detail Rc amplifier
Bilkul sahi kaha kisi me nhi di aise information thanks sir
Thank you sir coming follow karne ke liye mai ne hi Kaha Tha mp Fire ke class ke bare mein video banane ke liye 👌👌👌👈
Sir how can find capacitor polarity -ve +ve. Remove the rapper, and without multimeter ?
CRO is required
Amplifier is also used in d.j ...
Bt another device is also used in place of amplifier also known as mosfet 4 good voltage gain...can we say class D amplifier will be
mosfet......
Well explained bro
mixerka bareme bhi batauna sir
Good work
Hello sir . discuss analysis procedure of a power amplifier?
Sir please " transistor as a amplifier " k upar video banaye......🙏 TH-cam mai bohot dhunda par video dek k samajh hi nehi a raha sir ap please please sir transistor as a amplifier k upar video banaye
🙏🙏🙏🙏🥺🥺🥺
Pls pls sir
Thank you sir
sir how you make your videos. which software tool you used
which class is best for high quality audio?
Sabse best konse calss ki amp rehti low distortion,best tone best laoudness
To achieve the best combination of low distortion, excellent tone, and high loudness in an amplifier, the Class A amplifier is often considered the best option, especially for audiophiles who prioritize sound quality. Here's a breakdown of the different amplifier classes and their characteristics:
1. Class A Amplifier:
Low Distortion: Class A amplifiers are known for their very low distortion because they operate in a linear region, where the active device (transistor or tube) conducts throughout the entire waveform cycle.
Best Tone Quality: These amplifiers produce a smooth and natural sound with excellent tonal accuracy, making them highly favored in high-fidelity audio applications.
Moderate Loudness: While Class A amplifiers can provide good loudness, they are not as efficient as other classes, meaning they may require more power to achieve the same loudness as other amplifier types.
Efficiency: Typically low (around 20-30%), meaning they consume more power and generate more heat.
2. Class AB Amplifier:
Low Distortion: Class AB amplifiers offer a compromise between Class A and Class B amplifiers, with better efficiency than Class A while still maintaining relatively low distortion.
Good Tone Quality: They produce good tonal quality, though slightly less pristine than Class A.
High Loudness: Class AB amplifiers are more efficient than Class A, allowing for higher loudness without needing as much power.
Efficiency: Better than Class A, usually around 50-70%.
3. Class B Amplifier:
Moderate Distortion: Class B amplifiers are more efficient but have higher crossover distortion because each device conducts for only half of the waveform.
Moderate Tone Quality: The tone quality is typically less refined than Class A or AB, mainly due to the crossover distortion.
High Loudness: They are capable of producing high loudness due to their efficiency.
Efficiency: Higher than Class A and AB, around 70-78%.
4. Class D Amplifier:
Higher Distortion: Class D amplifiers use pulse-width modulation (PWM) and have higher distortion levels, although modern designs have significantly reduced this.
Decent Tone Quality: The tone quality can be good, especially with modern digital enhancements, but it may not match the warmth and clarity of Class A or AB.
Very High Loudness: Class D amplifiers are highly efficient, often above 90%, allowing them to produce very high loudness with minimal power consumption.
Efficiency: Extremely high, often 90% or more, which makes them ideal for portable or power-sensitive applications.
Summary:
For the best sound quality (low distortion, excellent tone): Class A is the top choice.
For a balance between sound quality and loudness: Class AB is a great option, offering a good compromise between efficiency and audio fidelity.
For high loudness and efficiency: Class D is ideal, though it may not offer the same tonal accuracy as Class A.
If you're an audiophile or working on high-fidelity audio projects, Class A amplifiers are generally the best choice for superior sound quality, despite their lower efficiency. For general-purpose applications where loudness and efficiency are key, Class AB or Class D might be more suitable.
