signals are then demodulated at the destination, so the recipient receives the original baseband signal.Dial-upmodems are a good example of this process, since they modulate and demodulate signals when they are transmitted and received. In fact, the word "modem" is short for modulator/...
This filtering stage before modulating the signal is also called pulse shaping as the data pulses are filtered out to produce a clean output signal with sharp rise and fall times, which helps in accurately determining the carrier frequency of the received signal. GFSK technique is useful and used...

The radiofrequency modulated signal is amplified to adequate strength by the RF PA once it is generated by the modulator and then sent by the antenna through the matching network. 2. Principle Take a close look at the green label. First, the RF signal enters from the left, goes through a...
A laser diode is a type of semiconductor diode that can generate laser light. The three conditions for generating laser light are: achieving population inversion, meeting threshold conditions, and resonance conditions. Because laser diodes have a very high sensitivity to static electricity, we should...
