I know there are commercial converters out there, but i want to build my own. I have an ARINC429 to RS232 converter transmitting data one way (not receiving any data), but my processor doesnt have a 232 serial port, it only has a 422. I need to convert the data transmitted from the 232 into a...
Hi everyone
I have a train of pulses coming in at a varying frequency. I want to design a circuit with a counter that counts these clock cycles on an 8 bit counter, having the counter end/reset every second, sending what has been counted to a processor. Any suggestions?
I need to build a circuit that convert frequency into a voltage, and the LM2907 circuit on page 16 of the **broken link removed** seems to do the trick. The frequency range is 0 to 2.5kHz, and i want to maintain the linearity and response time, but the circuit in the datasheet doesnt produce a...
The circuit i'm using is similarly matched to the circuit on page 6 of the LM3876 datasheet (minus all the optional components). i think it may be a problem with the board i'm using. I just tried the same circuit on another board and it worked fine.
Thanks, I tried feeding it a clean 400hz sine wave from the signal generator, but i get the same effect. It definitely has something to do with my amp configuration. It's just strange because yesterday it was working fine, but today, after i installed the bandpass filter, it started acting up.
I have 400Hz signal running into the amp, but the output is extremely noisy at the top peaks (bottoms are fine - see green signal). How do i fix this? I appreciate your help
NOTE: the sine wave is not a perfect sine because it is the product of a square wave i converted to a sine with a...
I have a 38.4khz crystal oscillator circuit that i have running into a 4060 ripple counter. i thought that if i used an AND gate on the Q5 and Q6 outputs that i would get a 400Hz frequency (2^5 + 2^6 = 96; 38400/96=400), but i'm getting a 350Hz with a 25% duty cycle. I need to divide the...
