ABSTRACT:
A continuously tunable function generator comprises a first function generator (10) with a triangle voltage generator including a comparator (24), which controls the commutation of a capacitor (14) from a charging phase to a discharging phase and vice versa in relation to an upper and lower preset amplitude value of the voltage at the capacitor (14). The triangle voltage (50) arising at the capacitor (14) is supplied to a second comparator (32) of another triangle voltage generator. The second comparator (32), commutates a second capacitor (38) of the same capacitance as the first capacitor from the charging phase to the discharging phase and vice versa. A reference voltage corresponding to the mean value of the upper and the lower amplitude value is applied to a second input of the second comparator. The charging currents and the discharging currents are identical, constant, and adjustable for changing the frequency of the triangle voltages. The capacitors (14, 38) are series-connected to sine function networks (30, 48) to produce sine and cosine wave output signals.
