Re: Need help on decoder
Which mean i have 2 sets of ( 5 to 32 decoder) ?
each decoder is having 5 address lines and 32 output data line?
Is it what you trying to say?
Or i should say a decoder has 10 input address lines and 1024 output data lines?
Guys,
I'm facing problem in the oscillator design by using the ADS. I'm trying to design an fix frequency oscillator (colpitts) working at 90Mhz.
In in the initial stage , I set my biasing current at 10m and Vc at 5V for the transistor 2n3904. Then i try to make the amplifier to perform at...
Hi all,
Really need help from u all. I've searched through the web, there were no topic teaching how to calculate all the component (Biasing resistor, colpitt frequency, coupling caps)value for below VCO design. This is the common model VCO pattern however i still cannot get it in detail.
Pls...
Hi guys, just wanna ask is below are correct?
ADD Bx,1234.
Using --> "ADD immed to reg/mem 100000sw mod000r/m [addr] data"
then 1000 0001[SW] 11[mod] 011[BX] 110 [direct address]
opcode = 81 DE H
Is is correct?
How about MOV [1234],AX?
Hi all,
I'm new to smith chart, i would like to know how to draw gain circle and noise circle on Z-Y smith chart.
Here is the data i got
For noise :
Centre of noise circle = 0.11<-145 deg, Radius of noise circle = 0.2847
Centre of gain circle = 0.44 < -149 deg, Radius of gain circle = 0.3875
Thx Tony. Do u hv any suggest on VCO? i've searched through the google, there were lots of oscillator design, colpitts (series or paralle) , Hartley. I've no idea which 1 i should choose.
Is there any simulation could be used before going to actual design?
I;m currently using ADS software...
Hi all,
I;m new to FM design. In fact, i;m still fresh to learn. My supervisor has told me to try achieve the modulation index, B ~ 5.0 (if possible).
My project is basically design a FM transceiver.
Input : microphone (human voice)
Output (TX) : able to produce the (human speech)
Design...
Hi all,
I'm doing a FM tranceiver project. The FM TX is required to produce output frequency of 40.x Mhz which is ISA band. The TX is also required to stick with VCO design. I;m stuck with the design.
Any 1 have ideas about it?
Hi all,
I'm doing a project of designing a FM TX and RX circuit without using any advance IC. The desire frequency band would be ISM band which is 40.xx Mhz.
I;m looking for help to design a stable FM tx and RX circuits. It would be great if you could share me the info.
Thx
Guys i still dun understand the band pass design in below attrached circuit.
the 1st IC1A and IC1B opamp hv , FL and FH at 1.59hz.
FH = (1/[2(pie) 10mic x 10K]) = 1.59hz
FL = (1/[2(pie) 0.1mic x 1M]) = 1.59hz
how come both cut off frequency at 1.59hz? if this is the case, the bandwidth =0 hz...
