Abstract :
There are situations in which it is attractive to use digital hardware in the synthesis of complex analogue waveforms. A design philosophy of using a digital implementation as far as possible may lead to simpler circuitry and give improved control over the parameters of the waveform. The authors propose such a simplified approach to waveform synthesis, describe the filtering problem that arises and put forward solution to it. The design and implementation of a minimum shift keying (MSK) digital modulator is used as an application example
