Title: Frequency divider
IPC: H03K23/52
Filed: 1972-10-25
Abstract: 1400849 Semi-conductor bi-stable circuits RCA CORPORATION 25 Oct 1972 [26 Oct 1971] 49173/72 Heading H3T A frequency dividing bi-stable consists of two cross-coupled exclusive NOR gates (Fig. 1, not shown) or exclusive OR gates, one gate responding faster to rising edges and the other to falling edges. In Fig. 3, one exclusive logic gate 10 consists of F.E.T.'s 50-53, the other 12 of F.E.T.'s 54-57; and an inverter 76 connecting the output of the other to an input of the one consists of F.E.T.'s 58, 59. Supposing outputs B, C to be high and low respectively, then when A goes high (time 1, Fig. 2, not shown) F.E.T. 55 makes node 75 high because it is held on by C. Gate 12 responds faster to positive edges of the input A than gate 10, by suitable selection of F.E.T. parameters. The high level at 75 turns on F.E.T. 59, and B goes low and is transmitted through F.E.T. 51, held on by A, to hold C low. This condition is thus stable. When A goes low (time 2), and because gate 10 responds faster to falling edges, both F.E.T.'s 50, 51 are off, and both F.E.T.'s 52, 53 being complementary to 50, 51 are on, so that C goes high. F.E.T. 54, being held on by A (low) passes C (high) to node 75 to maintain B low. When A goes high again (time 3) FET's 54, 55 go off, F.E.T.'s 56, 57 are both on, and node 75 goes low (-V R ) to turn on F.E.T. 58 and make B go high. A holds F.E.T. 51 on to pass B (high) to node 16 and hold C high. Finally A falls again (time 4) and F.E.T. 50 which is held on by B (high) makes C go low. F.E.T. 55 conducts C (low) to node 75 to hold B high, this being initial, stable, state. The described derivation of parameters for the F.E.T.'s, necessary for the different speeds of response of the gates 10 and 12, shows F.E.T.'s 51 and 54 to be always of relatively high impedance, whereby they may be omitted (Fig. 4, not shown).

As described a binary "1" is represented by a transition at the middle of a cell period T and a binary "0" by no transition except when followed by a further "0" when a transition occurs at the start of a bit cell. The maximum time between the transitions is then 2T=T M . An address marker is derived by omitting the central transition in the code 1001, this giving an interval of 3T between successive transitions. An interval in excess of 4T is taken to indicate absence of data. To correct for skew in data recorded in parallel channels the address marker may be simultaneously recorded on all channels, each channel being read out to an associated shift register.

During a second phase of the adjustment the output of the equalizer is fed to a threshold detector 15, to detect the nominal signal amplitude, and an error signal is derived between the input signal and output signal of the threshold detector and the error signal correlated with the signals at the delay device taps to provide the adjustment signals for the equalizer multipliers 26. As described signals are fed to the transmission system via a precoder (3), Fig. 2 (not shown), and a transmission filter (5) to provide partial response transmission and recovered therefrom via a reception filter (7) and decoder (9). During group delay equalization the characteristics of the filters does not have to be compensated and therefore an inverse filter 12, having a characteristic which is inverse the characteristics of the transmission and reception filters, is placed in circuit. In an alternative arrangement the filter 12 is omitted and a model filter of similar characteristic to that provided by the transmission and reception filters is inserted between the generator 16, supplying a replica of the transmitted test signal, and the input B of the equalizer 13. The multipliers 24 of the correlators may act on analogue signals or only on the polarity of the signals, in which case they comprise Mod-2 adders. During the first adjustment phase the difference circuit 14 is switched out of circuit then after a predetermined time, the switches 18, 19, 34, 35, are operated to cut the inverse filter 12 out of circuit, disconnnect the local generator 16, and put the error signal determining circuit 14 into operation. The detector 15 may be a zero slicer or a multilevel slicer depending on the number of possible levels of the transmitted signal. During the second phase of the adjustment the reference signal from which the error signal is derived may be taken from after the decoder 9 in which case the reference signal is applied to the subtractor 14 via a coder (33), Fig. 9 (not shown), identical to the coder used at the transmitter and a model filter (17), providing a partial response characteristic.
