Abstract: 1450959 Limiters; synchronous detectors RCA CORPORATION 26 Oct 1973 [6 Nov 1972] 49894/73 Heading H3T A limiter comprises a pair of reversely-poled diodes 1, 2, Fig. 1, connected in parallel between the two inputs 7, 8 of a differential amplifier 6, an input signal being applied by source 5 to one input 7 of the amplifier, while the other input 8 is connected by means of a resistor 11 to reference potential, point 10, to which the stray capacitances 3, 4 of the diodes 1, 2 are in effect connected: the impedance of the source 5 is less than that of the stray capacitance 3 coupled to input terminal 7 at operating frequencies, and the resistance 11 has a stray capacitance 12 and is of an order of magnitude larger than the impedances of the source 5 and the means coupling the anode of diode 2 and cathode of diode 1 to the input terminal 8. The arrangement is intended to prevent appreciable modification of the frequency and phase response due to the stray capacitances 3, 4, 12. As applied to a synchronous detector for video signals, I.F. signals are fed to a balanced amplifier comprising emitter-followers 108, 109, Fig. 2, via tuned transformer 105. Emitter followers feed a further stage comprising transistors 111, 112 in common-emitter connection with tuned circuit 115 as collector load, which in turn feeds cascaded emitter followers 116, 124 and 117, 125. On each negative halfcycle of signal applied to transistor 124 or 125 the transistor cuts off, the other transistor of this pair simultaneously conducting on the corresponding positive half cycle of signal, which is limited by diode 122 or 123 as the case may be. The limited output from terminals A, A<SP>1</SP> forms the carrier wave input to the synchronous detector formed by emitter-coupled pairs 131, 132 and 141, 142, modulated signals being fed from the emitter-followers 108, 109 to further emitter-follower stages which drive the transistors forming the emitter-circuit paths of emitter-coupled pairs 131,122 and 141, 142 Aresistor 121 in series with the diodes 122, 123 is chosen to be of such a value that the effective phase-delay is constant for all peak carrier levels (Fig. 3, not shown): alternatively a separate resistor may be arranged in series with each diode (Fig. 4, not shown). The diodes 122, 123 are preferably Schottky barrier diodes.

Abstract: 1,086,846. Single sideband amplitude modulation. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Dec. 3, 1965 [Dec. 4, 1964], No. 51488/65. Heading H3R. In a compatible single sideband modulating system a phase-modulated wave is synthesized from separate components which are added together and amplitude modulated. In one example the phase-modulated wave where the coefficients c and d are chosen to give the desired values of the coefficients a. In the drawing a generator G derives carrier frequencies 4/3#, 1/6#, and 1/3#, from a common source, and a modulation is applied to terminal E of a single sideband generating circuit EM to produce an output m cos (#/3 + w)t, where m is the degree of modulation and w the modulation frequency; this output is added to the #/3 carrier to produce three signals the coefficients d being adjustable by T1 - T3. In channel III this signal is cubed in unit K to produce #3, in channel I the signal is mixed with the 4/3# carrier in M1 to produce #- 1, and in channel II the signal is mixed with the #/6 carrier in M2 and squared in unit Q to produce #2. Each channel includes appropriate filters F, transit time equalizing networks L, and regulators R for adjusting the coefficients c. The signal # passes through a limiter B and amplifier V to a modulator M4 where it is amplitude modulated by the original modulation recovered from the output of EM by demodulator D. Non-linear networks N1-N3 may be provided to make the output signal # more nearly equal to that desired. It is shown that the coefficient C 2  is small so signal # 2  may be omitted; a further signal component # 1  = C 1 [cos #t + d 1  m cos (# + w)t] may be included instead of or in addition to # 2 .
