hi i'm from malaysia...
i need ur help...how can i design the transmitter and receiver using phase locked loop (PLL)
if appropiate, i need the block diagram of each module such that the mixer, osc, amplifier, mixer etc. and also the circuit and list down all the components.
this circuit will transmit the digital signal and the output also in digital. digital in and digital out. the frequency that will use is in High Frequency (HF) 3-30Mhz. the transmitting distances is about 10km. the modulation techniques that i'll use is FSK ...but do not decide whether PSK or FSK...can u give me the explanation on the FSK and PSK circuit for this transverse circuit..
tQ,
