[@AnandKumar-oh7zv]

sir plz correct one thing ;
V" = 1 when cos(theta) > 0; (you have written cos is >1)

[@EngineeringFunda]

Yeah, thanks for your kind reply.

[@deepakprasad2566]

your all videos are V.V.V. valuable videos........

[@madukannegha2492]

Thank you Prof for your inspiring lectures. Please can you explain how to shift a carrier signal by ninety degrees.

[@EngineeringFunda]

Phase shifter can do this. we cannot have RC phase shifter for it.

[@adarshachatterjee1220]

sir i think that will be +90 degree phase shifter...please check

[@averagepanda5971]

equation generated in nbfm generation doesn't contain kf? is it wrong?

[@meghashaw4563]

thank you so much sir

[@surbhisinghal3180]

Sir indirect method konse hote h NBFM or WBFM generation k?

[@siddartharaju4444]

good evening sir could you please upload electronic devices and circuits interview questions in engineering funda app

[@EngineeringFunda]

It is covered in solid state device subject.

[@alloc7260]

Can you please explain working of band pass limiter in details!

[@amandeo7185]

sir there will be +90 phase shift

[@ahmetciftci9035]

if you shift cos function by -pi/2, it becomes sin function not -sin, please correct this one

[@zenowing5155]

kf kahan gya sir final output mein

[@azizgundogdu9916]

9:50 cos(theta)>1 ??

[@qoimoicom]

how cos theta >1 10:00

[@EngineeringFunda]

It is cos ○ > 0, but by mistake I wrote 1.

[@vatsguru2004]

sab gadbad ho gaya

[@EngineeringFunda]

What happened

[@vatsguru2004]

Where that eqn came from
there should be 2piKf(at) where is that. NBFM ka eqn bhi nh smjh aaya... koi or tareeka.

[@abhishekdey7311]

@@vatsguru2004 previous video mein jab ec cos omegac t - kf gtsinwt likha tha narrow band ke liye wohi hai
