So the bandwidth increases due to frequency selected by the code. But why do we need FHSS
Thank you sir😎

Superb explanation..
great video sir! and very good explanation like always. But I have a doubt @ 11:10 you have said that in fast hopping Tc < Tb. However we are sending 8 bits in one cycle, then wouldn't Tc > Tb?
Nope
After watching the next my doubt got cleared.
super thalaivah
Your positive comments motivates me, Thanks and welcome 🙏
Sir plz make video on CDMA
The women invented this technology (Hedy Lamar) was also an actress
💥💥💥💥💥❤
Your welcome
Sir,Tc and Tb are the terms related to digital systems,why you use in FHSS where analyis for analog system is there.i mean why don't u use Bss and B for L in FHSS rather than Tc and Tb to explain fast hoping and slow hoping.
I think you may have a mistake near the end. You said that there are 625 frequency hops per second. However, there are 1600 frequency hops per second. Each hop has duration of 625 us.
Yeah
Sir In real practice, how they use different frequencies for different channels and vary them too with time. Do they use pcm modulation or real pattern generator. What's the main reason for changing frequencies with time.
Bluetooth frequency can hop 1600 times per sec
Can someone explain again what coherent detection is and why FHSS must use it?
Whether this video is useful( helpful) for mcq's ???? Pls reply sir
Your concepts will get clear.
@@EngineeringFunda ok sir tq

Is there is possibility of collision in FHSS?
How th code is selected which is used for selecting the carrier?
can u please suggest a text book for both analog n digital communication for isro exam?
What the name of the book which you explained from it ?
Now. What is tc tb

There is no receiver part explanation so is ok from exams
This is perfectly fine dear
Frefer😅😅😅
that woke me up 😂
Sir is this topic is enough for 7 marks?
It's complete information. So it is more than enough for it.
@@EngineeringFunda thanks for response
Sir what about the reciever
