Web2 jan. 2024 · As you can see, the minimum bandwidth required for transmission is equal to the baud rate. Example 4.3-1 Find the bandwidth for an ASK signal transmitting at 2000 bit/s. Transmission is in half-duplex mode. Solution In ASK the baud rate and bit rate are the same. The baud rate is therefore 2000. Gaussian minimum-shift keying, or GMSK, is similar to standard minimum-shift keying (MSK); however, the digital data stream is first shaped with a Gaussian filter before being applied to a frequency modulator, and typically has much narrower phase shift angles than most MSK modulation systems. This has the advantage of reducing sideband power, which in turn reduces out-of-band inter…
