Title: An arrangement and method for delaying an electrical signal
Inventor: DILLENBURGER WOLFGANG
IPC: H04N9/64
Filed: 1970-08-19
Abstract: 1,260,779. Electromechanical delay lines; colour television. FERNSEH G.m.b.H. 19 Aug., 1970 [20 Aug., 1969], No. 39863/70. Headings H3U and H4F. To enable a delay device comprising piezoelectric transducers mounted on a glass delay body to simultaneously delay two signals, at least one of the signals having a wider band than the band width corresponding to the fundamental frequency of the transducers, the signal (or signals) having the wider band is modulated on a carrier frequency which is an odd multiple of the fundamental frequency thereby increasing in a similar proportion the signal band width which the delay device may transmit. Fig. 1 shows the delay line, 4, employed in an arrangement for compensating signal deficiencies of a colour T.V. signal FBAS taken from a magnetic tape. The delay line 4 has a fundamental frequency of 4À43 Mc/s. and a band width of Œ1 Mc/s. The signal FBAS consists of a luminance signal and a carrier frequency modulated chrominance signal having a carrier frequency of 4À43 Mc/s. and a band width of Œ1 Mc/s., this latter being separated by a filter 1 and supplied to an adder 3. The luminance signal has a band width of 5 Mc/s. and is modulated in the modulator 2 on a carrier frequency of 15 Mc/s., this frequency being about three times the fundamental frequency, 4.43 Mc/s. Thus the delay line may transmit a luminance signal having a band width of Œ3 Me/s. The delayed chrominance signal Cr is derived from a filter 5 and the delayed luminance signal Y from a demodulator 6. In another embodiment (Fig. 2, not shown) the arrangement is employed for the vertical aperture correction of a colour T.V. signal. In this embodiment both the input signals to the delay device have a greater band width than the band width of the device at its fundamental frequency. Accordingly, one signal is modulated on a carrier having a frequency three times the fundamental frequency and the other signal is modulated on a carrier having a frequency five times the fundamental frequency.
