pabx specification
Guys need your advice...
My company would like to upgrade an analog pabx system...
I'm no good in electronic communication...
What are specs that need to be considered in upgrading or buying such an analog PABX system. Currently my company use ALcatel Lucent analog Pabx...
Guys,
I want to buy p.a system that suitable for indoor and also can be used for outdoor (500 audience). My budget is around 10000 USD or RM40000 which include item below:
- Digital mixer (12 channel and above)
- Amplifier
- 1/3 octave Digital Equilizer
- 2 loud speaker (400W RMS and above)
- 1...
Guys please help...will there any problem if Lead Free PCB being process using Leaded Solder Paste...?
Is it the joint is will be strong enough?
Will this caused unsoldered finepitch lead issue?
Please help to advise guys.
Thanks in advance.
Basically if you want to make things that can recognize color then you can use the LDR but put a color filter on it.
Use Basic comparator circuit to compare voltage from the LDR with the threshold voltage that you can adjust depend on each color using variable resistor.
If you still have any...
Guys need your advise on circuit attached herewith:
Is it if we change R83 to such a low value like 100 ohm 330 ohm will cause Q24 is not strong enough to pull the signal low?
If yes why? Can you guys please explain this?
Please advise guys.
Thanks in advance.
Re: servo motor
Potention meter being connected to the shaft. When shaft rotate the potentiometer also will rotate.
I am not sure signal that the potentiometer send back to the circuit whether varying voltage, varying oscillation or etc.
But the concept is when there is PWM signal to the...
Re: servo motor
For servo motor there is potentio meter circuit that will be connected with the DC motor shaft to control the angle of the rotation. If we give such a PWM it will rotate to the certain angle depent on the PWM width.
That is the different between DC Motor and DC servo motor...

Servo motor can be controlled by PWM.
Yes it is a close loop system.
It being incorporated with potentiometer to control the angle of the rotation.
It can stop and hold its position not like DC motor which we need to hold it mechanically.
DC servo motor usually...
Can we implement And Gate Function in 2 to 1 multiplexer....?
Base on the Boolean Algebra seem like cannot.
Please advise guys.
For And Gate:
z=AB
For 2 to 1 multiplexer:
z=(A.Sbar) + (B.S)
where S is the selector.
Or am I wrong on this.
Re: Bulk of NMOS tied to different potential instead of grou
But can you please see this link:
**broken link removed**
Base on this link we can connected the bulk to other potential instead of ground.
Why you said it NMOS bulk cannot tied to different potential than ground?
Can you please...
