Sorry IanP can you describe with more details? perhaps with a simple schematic diagram?
My condition is like this. I connect a decade counter 74ls90 with the latch 74ls374 and a bcd to 7 segment decoder 74ls47 and finally the 7 segment display. When i power up the circuit, the circuits start to...
I have a square waveform as in the 1st figure which is not a smooth waveform. It has a high peak that i dun want in my real circuit. I want it to be a smooth square waveform as in the 2nd figure. So how am i going to convert the square wave with the peak to a smooth square waveform? Please...
Suppose i have a frequency and i want to count it by using a decade counter, latch, BCD to 7 segment decoder and finally display the count on 7 segment display.
Theoretically if my input frequency to the decade counter is 1Hz, it will count 1 in 1s and if 10Hz, it will count 10 in 1s.
My...
Is there any method to convert a square wave signal into a fixed DC signal? Say if i have a +1V high level and 0V low level square wave, how am i going to convert it to a DC level +1V signal? Will it works if using a low pass filter? If yes, how's the circuit looks like and what is the value of...
Ok.. the square wave input wont work for LM331. Can i convert the square wave input to a DC level signal? Say if i have a +1V high level and 0V low level square wave, how am i going to convert it to a DC level +1V signal? Any suggestion so that i can feed this input into my LM331?
I think i got what you mean. The input after passing through the and logic and switch is actually same with a square wave input. But since the square wave input is not working, i dun think connecting a AND gate there will make the VFC working properly?
Because the input is coming from my output of AD633 analog multiplier which is a square wave. The output of AD633 analog multiplier is converted into frequency. So the input to the frequency converter is a square wave =)
Hi all,
I had construct a voltage to frequency converter using LM331. The circuit can be found in Figure 3 in the LM331 datasheet which you can found it at **broken link removed**
I use Proteus to simulate through the circuit and it works fine with a DC input signal (0-10V). But when i change...
