| 4617537 | Method for digital quadrature amplitude modulation Spectrum-converting digital filters are employed for quadrature amplitude modulation. Given the method of the invention, the frequency of the two carrier oscillations residing at 90° relative to one another amounts to one-fourth the sampling frequency an... | 10/14/1986 |
| 4529950 | Digital phase and amplitude modulator A digital phase and amplitude modulator with a code conversion circuit having several digital inputs able to receive digital data and the same number of outputs supplying code converted digital data, a generator of at least one carrier having at least one... | 07/16/1985 |
| 4380746 | Pulse modulator using capacitor charging and discharging circuits A self-starting, non-latching, pulse modulator which will function as an analog divider of first and second input quantities, or as a linear pulse period modulator responsive to one of the quantities, or as a linear pulse frequency modulator responsive to... | 04/19/1983 |
| 4328470 | Pulse modulated IMPATT diode modulator A high efficiency modulator circuit for modulating a microwave oscillator having a negative resistance device comprising an IMPATT diode disposed within a resonant cavity is presented. A first transistor comprising a relatively high output impedance, fast... | 05/04/1982 |
| 4159448 | Communication systems A pulse modulation system in which both ends of the pulses of a train can be modulated in time relative to time marker signals, permits establishment of a four-channel, time division, duplex communication system on a single radio frequency carrier. The mo... | 06/26/1979 |
| 4037173 | Multiple carrier modulation synthesis Two carriers are gated on and off in an alternating sequence. The same group of different digital sample point values signifying various modulation levels required for each carrier at successive points in time are read out in timed sequence and applied to... | 07/19/1977 |
| 4017810 | Voltage controlled oscillator A plurality of window comparators and voltage controlled oscillators are arranged to receive analog input signals which are converted to output frequencies that are linearly proportional to the analog signals over a substantially infinite amplitude range.... | 04/12/1977 |
