Dear All !
If the audio signal is squared in the matlab and then it's dc component is removed .What should be the response of audio after the inverse fourier transform. What exactly is happening , can any one explain .? Squaring in the time domain means that we are taking power of the signal or...
I want to ask if we have an audio signal ,and we take it's fourier transform using fft in MATLAB and then increase the amplitudes of the frequency bands as mentioned above, what do u suggest should happen to the original audio when one listens back this audio. Like what i am getting is...
Hellow Every body !
can anyone tell me if we increase the amplitude of a band of frequencies such as the lower frequencies and higher frequencies leaving aside the mid spectrum .
e.g. if I increase the amplitude of freqencies below 150Hz and above 4kHz what effect should it make on the audio...
I intend to ask, if the output sound is behaving correctly . I want to get the concept of amplifying lower and higher frequencies only leaving aside the middle spectrum
hello every one .
here is another relevant question . .. Can any one tell me if I want to control the loudness of selective frequencies what effect should that make on the sound . eg if I wish to increase the amplitude of frequencies below 200 Hz and above 5kHz in an audio sample what kind of...
Hi All ,,
I have an assignment to submit where I have to do the frequency shifting by a factor of 3 or 0.7 . I need to ask if what kind of output should I have after this process .i.e. should the output be as if a man's voice is changed to women or something like that. .
Thanking in...
HI !
I recently done the project of designing CPW passive elements for 2-5 GHz , can any one tell me what should be the s-parameters of a resistor , should it be like low pass or what ,

Re: LAyout for microstip line based microwave amplifier circ
Hi !
Can any one look at the layout and let me know what changes I need to make, where I need to do via , and how to do that. plz . .
Re: LAyout for microstip line based microwave amplifier circ
do I put the juntion between the radial stub and adjacent transmission line as well.
.................. plz
Hello every one,
I have a simple circuit made for the microwave amplifer design , see the pic , I just need some what similar microstip layout for this schematic.
the schematic in microwave office looks like .
can u tell how should the layout look like , i v got it like this , (other than...
Hi
Thanks for the reply but , I've gone through the lecture already , I've confusion regarding using absorbtion method or resonat approach. so far as I tried , it could be done using resonant approach and not absorption ..
but , then I mean to say that u 've got capacitance on both sides...
Hi ,,
Can any one guide me how to do 2 element lumped elements matching inorder to match a source impedance of 25-j15Ω to 100-j25Ω.
frequency of signal is 60 MHz , although I just need the procedure .
Limitations (we have to do it using 2 lumped elements and not 3).
Please if any one can...
Hi to all !
I am new to the subject of microwave circuit design , Ive been given assignment to desing the amplifer at 4 Ghz frequency , how do I get started , I ve chosen the appropriate transistor , how to design the biasing. Plz guide
