I have some problems related with OP-AMP circuit.
This circuit is composed of two OPAMP stages.
but first amp's noise amplified by the next stage amp increase to the signal level
A capacitor in between these amp has used to suppressing noise
I want to know how to make it work properly.
For...
I want to design some circuit which is drive 4 of led-diodes with npn, pnp, diode.
In my project our cpu has used most of its ports except only 2 ports.
And we have to control 4 LED with 2 ports
I want it operates separately in 4 conditions such as (High, Low),(H,H),(H,L),(L,H),(L,L)
I have...
so fast answer~
Thanks a lot~

Thank you for your clear answer.
But I'm Korean and I don't know the word 'decifer'...
I want know which modulation is used. (AM or FM)
In the picture this circuit is wireless microphone and boxed part is 100MHz oscillator. audio signal is amplified and then modulated from this oscillator.
help me.
Exactly, operating frequency is FM band and this circuit is FM Transceiver. but I...
