Abstract
An animal is trained using a remote transmitter and a collar-mounted receiver carried by the animal by selecting one of a plurality of desired stimulus levels by a stimulus level control of the transmitter. Information representative of the selected desired stimulus level is transmitted to the receiver and demodulated to produce a digital signal representative of the selected stimulus level. A microprocessor in the receiver operates to generate as an output a first stream of pulses of constant duration at a frequency representative of the selected stimulus level. The first stream of output pulses is filtered to produce a second stream of pulses the widths of which are representative of the selected stimulus level. The second stream of pulses is applied to the control electrode of a switch coupled in series with a primary winding of an output transformer of the receiver to repetitively turn the switch on for durations equal to the width of the pulse of the second stream and causes the amplitude of voltage pulses produced between contact electrodes connected to terminals of the secondary winding of the output transformer to be representative of the selected stimulus level.
