Abstract : Disclosed is a transistorized sonar transmitter which includes a power supply, a variable frequency, variable power, switching output stage, the switching of which is actuated by suitable drive signals from a control signal generator and amplifier. The power output from said switching stage is controlled by a time-ratio-control circuit which regulates the voltage thereof by means of a variable duration TRC drive signal from said control signal generator and amplifier, the duration of which is proportional to the power output thereof.
