Synchronous and asynchronous modulators In computer network in hindi

Synchronous and asynchronous modulators In computer network in hindi Synchronous aur asynchronous modulators communication systems mein upyog hone wale do alag approaches ya techniques hai jo modulation ke liye istemal hote hain. Inmein antar unke bhaagon ke tarike mein hota hai, jisse modulating signal aur carrier signal ka timing handle kiya jata hai.

Synchronous Modulation (समकालीन परावर्तन): Synchronous modulation ek aisa technique hai jahan par modulating signal (data signal) aur carrier signal ka timing synchronize ya samanvit hota hai. Is technique mein modulating signal ko equal time slots ya intervals mein divide kiya jata hai, aur har interval ek specific portion ko represent karta hai carrier signal ka.

Synchronous modulation mein, modulating signal ko regular intervals par sample liya jata hai, aur har sample ka istemal carrier signal ko modulate karne ke liye hota hai. Yeh samanvit hona ensure karta hai ki receiver original signal ke timing aur structure ke baare mein jaankar modulated signal ko sahi tareeke se decode kar sake.

Asynchronous Modulation (असमकालीन परावर्तन): Asynchronous modulation ek aisa technique hai jahan par modulating signal (data signal) aur carrier signal ka timing synchronize ya samanvit nahi hota hai. Is technique mein modulating signal ko equal time slots ya intervals mein divide nahi kiya jata hai, jaisa ki synchronous modulation mein hota hai.

Asynchronous modulation mein, modulating signal ka timing carrier signal ke saath synchronize nahi hota hai. Modulating signal ke changes ko directly aur as-is carrier signal par apply kiya jata hai. Iska matlab hai ki modulating signal ka har sample carrier signal par independent tareeke se modulate hota hai, bina unhe specific time slots mein map karne ki zaroorat ke.

Chaliye, hum synchronous aur asynchronous modulators ke beech ke antar ko samjhte hain:

  1. Synchronous Modulation (समकालीन परावर्तन): Synchronous modulation mein modulating signal aur carrier signal ka timing synchronize ya samanvit hota hai. Modulating signal ko equal time slots ya intervals mein divide kiya jata hai, jo carrier signal ke specific hisson ko represent karte hain. Synchronization ensure karta hai ki receiver original signal ke timing aur structure ko sahi tareeke se jaanta hai, jisse accurate demodulation aur decoding ho sake.

  2. Asynchronous Modulation (असमकालीन परावर्तन): Asynchronous modulation mein modulating signal aur carrier signal ka timing synchronize nahi hota hai. Modulating signal ko equal time slots ya intervals mein divide nahi kiya jata hai. Modulating signal ke har sample ko carrier signal par seedhe aur as-is tareeke se apply kiya jata hai, bina unhe specific time slot mapping ki zaroorat ke. Asynchronous modulation mein modulating signal aur carrier signal ke beech me precise timing coordination nahi hoti hai.

Synchronous aur asynchronous modulators ke antar mein mukhya antar timing synchronization mein hota hai. Synchronous modulation mein modulating aur carrier signals ke beech mein strict coordination hoti hai, jabki asynchronous modulation mein aisa coordination nahi hota hai.

Synchronous modulation aam taur par un applications mein istemal hota hai jahan precise timing aur accurate demodulation zaroori hoti hai. Wahi asynchronous modulation simpler hota hai aur usko woh situations mein istemal kiya jata hai jahan precise timing mahatvapurna nahi hoti, jaise ki low-cost communication systems mein.
