Abstract
A frequency divider for a tone source for an Arabian scale in an electronic organ of the type wherein musical tone signals for a standard musical scale, musical tone signals higher than the same by 50 cents and musical tone signals lower than the same by 50 cents can be obtained from the output signal of a main oscillator. The output signal of the main oscillator is frequency-divided by at least one frequency divider to obtain an output signal. The aforesaid frequency divider comprises a counter and an AND circuit. An input terminal of the frequency divider is connected through the counter to an input terminal on one side of the AND circuit and is connected directly to an input terminal on the other side of the AND circuit.
Claims4
A tone source for an Arabian scale comprising a frequency divider including a counter, an AND circuit including two input terminals and an output terminal, and an input terminal connected through the counter to one of said input terminals of the AND circuit and connected directly to the other input terminal of the AND circuit, said counter being a 36 counter such that for every thirty-six input pulses to said counter thirty-five output pulses are produced to obtain musical tone signals at said output terminal which are lower in frequency by 50 cents.
