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

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.
