hello mam, thanks for the explanation , mam shouldn't the modulation index should be 1 . i think the wave is overmodulated
Hello, Dr.Aarthi, Your pre-emphasis(75us) circuit really works on LT-spice simulator. But I see a small error in the graphics. ( 1:38 ). The whole graph should be shifted to the right by approx. а half decade. The pre-emphasis now starts at ~400Hz (+3dB), but should start at 2.1kHz. Anyway. Another easier solution for pre-emphasis is to bypass(discard) L and mount in parallel to R4 a cap 7.5nF instead (for 75us time const). So we bypass the negative feedback and boost frequencies over f=1/(2*pi*R4*C) with slope 6dB/oct. Note that this can saturate transistor at some frequencies with so high (2V) input signal! Happy New Year and greetings from Varna, Bulgaria!
Kindly also upload SSB-SC
shouldn't fmax-fmin=2 delta(f) and not just delta(f)
yes.
Mam kindly also perform the Mixer Circuit experiment before the FATLAB.
2 and 6 pin are also connected using jumper wire right??
I never saw any modulated signal let alone the amplitude modulated!
I could not understand your doubt.
@@aarthig1 you didn't demonstrate the actual live audio AM modulated signal on scope. I was hoping you will have done it... Anyhow your video your choice
@@awaismushtaq5719 I have demonstrated in another video, link provided in the description for AM signal measurement.
@@aarthig1 OK! Will see! Thanks!
Super explanation madam
Excellent explanation. Could you please make the material presented in the video available? Thank you very much.
Can you send me a mail to achezian@gmail.com.Will share it.
nice video thank you maam
Thank you...
Maam u can try gate question?
We will try
Nice maam keep going
Thank you.
Very usefull mam👌👌🙏
Thank you...
Thanks ☺️ Easy
Welcome 😊
Nice Vedio maam
Thank you...
Crystal clear explanation mam⭐
Thank you
Thank you mam !! You made it simple saving our lot of time .Very helpful
Mam aage to btao...uske aage smjh nhi aa rha..
Can you text in english please
that video was pretty useful,thank you.but it would be more appreciated if we have some more explaination regarding the pwm and how the 555 timer works
Noted
Thanks mam
Most welcome 😊
what type of dioda using?
PN Diode
Nice explanation. Worked perfectly in LTSpice. Thanks.
Thank you for keeping the videos ma'am
You're welcome.
Hi, I can't see the circuit diagram. Would you give me the values of the resistors R1, R2, and capacitor that is connected in 5?
R1=R2= 6.8 k ohms and Capacitor value = 10 micro Farad.
@@aarthig1 Thanks!!!
Mam, please post all lab experiments in analog communications systems 🙂
will do it as soon as possible.
Easy to understand mam...
Great ! I am Electronics enthu. Can you please make a video how to design single tuned RF amplifier. How to design tank circuit L and C and all biasing.
Sure.will do it.
@@aarthig1 Thank you.
where is next part ?
