i found the solution. i'll use an op amp 741 and i'll set the gain between 0 and 1 whatever my application requires. that will solve my problem with the least effort. the resistive divider wont work for AC. its for DC
op amp attenuator
Hi, i'm working on a project and i need to change the voltage levels for some devices.... for increasing the level i use opamp bt how to decrease the level... say a device gives 5Vpp as output bt the device next to this only accepts 400mV signals.... so how to achieve this...
Power amplifier help
Hi people, i need to make a power amplifier for the following application. plz suggest me a simple as possible power amplifier which works in the audio range that is from 20Hz to 20KHz bcz my application works on 40KHz and 50KHz. i just need this plz help. thanks. and with...
l297 schematic
Hi, i have used L298 in simulation and in real. i have posted the config i used. and it worked perfect. and i just used 4 diodes. not more.
Hi, m trying to implement PLL for FSK demodulation. NE565 is very simple in use and has very simple formulae bt the problem is that m nt going on hardware. i just need to simulate first. i tried Proteus bt proteus unfortunately doesnt has a model for NE565.... see 'pic1' ...... so i need an...
Hi, i've been able to make an FSK circuit and its working good.....
now i've to send it in the air....... for wireless communication.... now the question is that if my FSK signal's low freq is 19MHz and hi freq is 20MHz (refer to the image i've attached, here i've kept a big difference in the...
Hi people, i have started to work on some my own stuff..... and there are often places when i have to make a bjt amp of the gain as required in the application....e.g., recently i made an oscillator whose amplitude was 0.8 V bt i need a amplitude of 5Volts so i need to place a amplifier of 5/...
