iset smps
can you please guide me to make SMPS of 440V and 5A with complete circuitry and parts that are readily avail....such that I can vary the coltage from 0V to 440V and current from 1A to 5A...
My need is urgent so please respond
Regards

i mean i want to create a band pass filter for ultra sound of 37-44 Khz; but have not succeded;
even if the ultrsound transducer is OFF, the receiver transducer receieves noise from environment but of less amplitude;
so any circuitry tips to select required band of signals?
should i try...
any one can condition the signal received from ultrasound transducer avoiding noise????
received wave is sine wave with lots of noise of noise
even the noise has same frequency of 40khz
but they slightly differ by amplitude?????????
any one has played with ultrasound?
lets talk &take it over
hi there
i am in same confusion to to get the band pass filter for my transducer
between 39-41 khz and central frequency 40khz;
and i want to use RC filter filter i.e. passive one;
can this give acuurate filtering;
should i use this type of band pass filter before LNA;
i am using LM833 as...
Re: somebody please help me about pc rf transmitter interfac
better read tutorials from mathworks.com of matlab;; by searching in serial port communication;
keep on talking and sharing ur new ideas and problems
Re: anyone suggest circuitry for CMOS to TTL logic conversio
Hey there AA1LL
May be i couldn't make you understand.
Or you might have forgot
1.Are you clear that the IC LM358 perfectly works as a separate module even with the circuitry as in the attachment;
But in the circuitry where it is...
Hi again guys n gals!!!
As shown in attachment below,
what the problem is input to opamp is 6-8v DC which is first case;
now since opamp is used as a comparator, it gives 4-5V output,which is desired;
BUT, even when input to the comparator is 200-300 mV still output is 4-5V.
Now, the more...
Hi !!!!!!! guys
Special thanks to IanP
and thank you A. Anand Srinivasan
Now can I share a new problem,
I am using a ultra sound transducer as input to a ckt as shown in attachment;
The required signal is sine wave of pk-pk volt 50mv;
and output of the circuit is dc of 6-8V as shown in...
clipped sine to square
No solutions at all
I can't get a complete square;
no improvement guys;
refer attachment:cry:
Added after 12 minutes:
Yes,I have noted this circuit in the same website;
can i use any opamp instead of 1/2 TLC93
TLV2470;
So, I have not tried it yet....
the input wave...
Re: circuit to measure flow of liquid using ultrasound
uh la la!!!!!!!
i thought making waveforms withs symbols were better but they were distorted.
so i have posted an attachment of schmitt trigger used with waveforms input and output and what is to be obtained.
so would you again look this...
clipped sine wave to sine
FIRST OF ALL,
THANKS A LOT FOR LENDING HELPING HANDS.
I THINK I COULD NOT MAKE YOU UNDERSTAND GUYS!!!
AS SHOWN IN ATTACHED FILE I HAVE CLIPPED SINE WAVE AND I HAVE TO CONVERT IT TO SQUARE WAVE FOR COUNTING ITS WAVE'S FREQUENCY.
ANY IDEA GUYS??????@...

WHEN I MAKE ONE INPUT...
I am having problem in finding velocity or flow of liquid
I have already amplified the received signal but since the sine wave detected is being clipped ;How can I measure the time period of frequency shifted signal;
Can someone suggest some pulse shaping circuitry to square wave or any other...
clipped sine wave
I am having problem in counting the period/frequency of clipped sine wave;
can any one suggest pulse shaping circuitry so that i can measure frequency;
Specially I had problem in calculating frequency deviation in flow measurement using ultrasound;
