Abstract: Amplification circuit, particularly suitable for use with a tire pressure reduction indication system, providing a pulsed output signal of predetermined frequency on receipt of a pulse input signal and a constant output signal for a change in D.C. voltage value of the input. The circuit may also include rejection means for rejecting input pulses below a certain amplitude, for rejecting changes in D.C. voltage level below a predetermined level or input pulses not having immediately preceding and following smaller pulses of opposite polarity.
