Today, SUPARCO AM Electronics Test was conducted for Karachi centre at SUPARCO HQ (Gulzar-e-Hijri, Scheme-33, near Maumiyat). Test timing was 10:30 but it started 55 minutes late at 11:25 because AM Electrical test was held earlier at the same place and it took time to clean up.

I don't remember all the questions but I will share what I can collect from memory.

Test:
Total 50 MCQS with 4 possible answers (a,b,c,d)
Total duration: 1 hour
Each correct answer will earn 2 points.
Each wrong answer will deduct 0.25 points.
No point will be earned/deducted for unanswered questions.

1 Charge of 1 coulomb is present in: 6.24x 10^18 electrons
2 Diode which removes a part (either positive or negative) is Clipper/Clamper/Limiter
3 F (hexdecimal) is represent in decimal as: 15
4 RCD is used in which configuration: bridge/pi
5 z-1 is used as a delay block
6 Minimum sampling rate of a 300Hz - 1.8 kHz 3600 samples/sec
7 Minimum sampling rate of a 300Hz - 1.8 kHz ( this question was repeated in question paper) 3600 samples/sec
8 Rainfall plays role in face off of radio waves of frequency above 100MHz/1Ghz/10GHz/100GHz
9 zener diode breakdown voltage characteristics as current increase: breakdown voltage remain same approx.
10 Optical sensor is composed of a)photodiode/b)phototransistor/both a & b/d) laser
11 In series RLC, where R=10, |Xc|= 20, |XL| = 20, and Vs=200, what is Vc 400<-90
12 For discreet time signal x(n), what will be x when n is not a integer undefined*/positive/negative
13 time scaling is Sampling/Upsampling/Downsampling
14 if a pole is on jw axis then system is marginally stable/stable/unstable
15 Transfer function is laplace transform of output signal/laplace of input signal
16 f(x) = x^5 -1 then what is f^-1(x)?
17 FPGA stands for Field Programmable Gate Array
18 MSI IC has built in what function? opamp/other options (i forgot)
19 The function of voltage regulator is to keep Vout constant when Vin or load current changes
20 ln (x-2) < 0 when 2<x<3
21 x3 - x - 11 = 0 (or any other 3rd order eq.), one of the roots is: (select 1 among) options
22 x3 + 3xy + y - 1 = 0 (or similar type eq.) , dy/dx is:
23 switching voltage regulator in pure sine wave inverter:
24 household wiring is of which type single phase 2-wire type
25 Data rate from QPSK of FM wave of 100MHz bandwith
26 Analog modulation which requires least power and bandwith: AM/SSB/DSB/...etc.
27 The channel which is open to all machines broadcast*/multicast/unicast
28 Computers connected to client in a certain way. (I forgot the exact question but its related to network topology) Computer network/Distributed System/..etc.
--------------------

Thankyou for the share... If anyone else have attempted Q's, please share it.

For Q6 & Q7:
A signal has frequency components from 300 Hz to 1.8 KHz. The
minimum possible rate at which the signal has to be sampled is
Sol:
B.W = 1800 - 300 = 1500Hz
m = 1800/1500 = 1.2 = 1 approx
Minimum Sampling Rate = 2*max freq / m = 2*1800/1 = 3600 samples/sec

For Q8:
At frequency over 10 GHz, rain and precipitation can influence the attenuation a lot; the effect of atmospheric attenuation between the source and destination over wireless communication.

For Q10:
Both (photodiode and photo-transistor)

For Q14:
As the poles are on the imaginary axis, the system is marginally stable.

For Q16:
f^-1(x) = 5sqrt(x+1)

The result will be announced on 19th of December Right, please tell me I do not remember

I am not sure but I think the same. I vaguely remember test result will be available on Wednesday, 19th of December. And Passing candidates will undergo psychological assessment right after the result announcement on Dec 21st. However, I'm also not sure about it.

The result has been uploaded at SUPARCO official website along with the date of psychological assessment date of recommended candidates.

Thanks brother, I gave the psychological test, lets see. Hope for the best.

can you please tell me psychological test? kia kia pocha jata hai and how to attempt it?

Welldone

Has anyone received interview call ? Please, notify when you do.
