PWM(pulse width modulation) modulation and ΣΔ modulation can transform arbitrary waveform into one bit signal stream. Therefore,both of them can drive the sonar transmitter. In order to compare the performance of these two modulations,this paper focused on five indicators to measure the performance of sonar transmitter's driving signal. The conclusion is that,in sonar transmitter applications,they have the same electrical efficiency,but ΣΔ modulation has higher output linearity and smaller harmonic distorti...
