I have used my small loop antenna (which has a main loop and a coupling loop that can be tuned using a variable capacitor) with an AM radio receiver to receive MW broadcasts. However, the small loop antenna which was made by me was not working properly but when I connected a ferrite rod loop...
I am trying to make a power wheel car remote controlled.
My setup is: I am using a 4 channel relay module to control the car's motor in forward reverse motion and the relay is getting the signal from a RC receiver. I have a 12V lead battery. The relay board and the receiver board needs 5v power...
I know its a bit janky but Ive just needed to make this door opener device remote control and for some reason, I cannot get this receiver to power anything even when both channels are on. Can someone help me?
I am designing a GPS L1(PWR=-160dBW) band Direct RF sampling receiver and the front-end:
(passive antenna + LNA(21dB) + BGA1(30dB) + jumper + BPF(L1(fc=1575.42MHz,BW=15MHZ) + BGA2 (30dB) + BGA3(30dB) + VGA(-13.5 to +18 Gain Control in 0.5 dB Steps) ).
all amplifiers are supplied with a +5 V...
Hi,
I have a project that i would like to complete.
i need to activate an LED light outdoors, whenever a designated vehicle comes within 200-300metres of the LED light.
i was thinking of using a simple 12v FM radio transmitter on the vehicle.
the LED would have an FM radio reciever tuned to...
I need your help in understanding how to simulate a timing recovery algorithm. I have already read a lot of literature but I have still doubts how it works.
Let me briefly explain my simulation:
Create a test signal:
BPSK, 1000 symbol with 16 samples
Raised cosine filter
Compute an amplitude...
Note: I've dabbled in electronics for many years, but I'm a newb when it comes to radio circuitry, so please forgive me for anything dumb I may say/ask.
I'm trying to design a system where I can send a single radio pulse (no complex information, just a single pulse) periodically. This pulse...
