excellent lecture, but i have some confused , if we apply input section 5V (high volt) respectively A and B , Then what will be the result or how will be the logic output value?
At more than .7 saturation region So u can take either .6 or .7 Because for large base current voltage between base and emitter .6 to .7 required to conduct
superb explanation mam....... we need teachers like u... thank u
Thanks 😊
Maam your explanation is very clear and straight. Thank you for teaching this topic 🥰.
superbbb, was wandering through videos, didn't get the right tutorial. But this one was what I was looking for.
Thank you dear
Nice video....
From Bangladesh
Thanks 😊
धन्यवाद
Thank you ma'am... really fantastic explanation.. keep posting helpful content
Thanku dear for feedback
Mam, please mention the superiority of optical logic gates over electronic logic gates and opto-electric logic gates
Superb Explanation 👌
Thanku so much
Keep watching to support my videos
Wonderful explanation
Thank you

Last case will be its explanation
thank you so much ma'am ❤️
😊
you have used Vbe = 0.7 v in TTL NOR GATE , Vbe = 0.6 in TTL NAND GATE. it's confusing . Which is right ????

thanks a lot. you deserve more views & subscribers !!!!!
@@moviesmania253 thank you
In all four combinations q1 is on . Right na
On off the pn junction is forward biased
At 12.:31 How voltage .2 volt? Please explain.
Mam in ttl at logic level one ke graph me voutput starting me constant Hota Hai kucch point tak Aisa Kyo please reply
Thanks mam💜
What is the importance of d1 diode?
It is used between both transistor so that at a time only one will on and other will be off
are ttl nand gate with totempole output and ttl not gate same maam??
No
Mam please explain me
At Q3 transistor pr humne 0.7v liya hai kayi bar 0.65v lete hai konsa kab Lena hai please explain??????
Dono le sakte hai
Actually for active region. 6 required
@@TechnoTutorials2783 thanks you mam 😊😊
Good morning 🌄 have a nice day 🌈
@@TechnoTutorials2783 I'm your student mam ,and I'm your sucriber also aur me apke videos dekhna psnd krta hu because aap bhut asha padte hai 😊😃
@@harshitsinghbanaswara2003 thanku
Mam please send the notes
Mam what is use of diode here
At a time either t3 will On or T4
By placing Diode between Transistor more voltage required to turn on upper Transistor
@@TechnoTutorials2783 Thank you so much mam
Exam day sae age is tarha ki justification boht achha lagta hae ❤️
