Abstract: An interface circuit for converting emitter coupled logic ( CL) signal levels to FET logic signal levels (e.g for a CMOS FET memory) comprises a small signal multiplier (20) for producing a single-ended clocking signal (ϕ) for FET logic circuit operation from complementary clocking signals (CS,  CS ) from an ECL and an FET dynamic sense amplifier (22). The multiplier (20) comprises an FET amplifier having an input FET (28) with its source and gate connected to input terminals for said complementary clocking signals. The FET dynamic sense amplifier (22) has a first input (23) for receiving a reference level (VREF) from the ECL circuit, a second input (25) for receiving a logic output signal level (ECL1) from the ECL circuit, and a clocking signal input connected to receive the single clocking signal (ϕ) produced by the multiplier. In operation, the dynamic sense amplifier_produces complementary FET logic signal levels (ADR, ADR ) determined by the potential difference between the levels (VREF, ECL1) applied to its first and second inputs.

Abstract: An adaptive radar system is presented which is capable of identifying interference frequencies and changing the system operating frequencies to permit radar operation in portions of the frequency spectrum that are free of interference. A time-integrating optical receiver (14,. 16) of electronic FFT is employed to detect those frequencies (17) where interference occurs thereby cueing the radar system to noise-free portions of the frequency spectrum. A digital computer processes the information from the optical or electronic FFT receiver to control system operation at those frequencies where interference has not been detected.

Abstract: A technique is disclosed for equalizing an incoming signal including quadrature-related carrier signals by forming the product of the incoming signal at at least one prescribed time and only one real-valued coefficient associated with each time. In one embodiment of the present invention, the equalized incoming signal (43) is demodulated (44) into a first pair of component signals (I, Q). At least one of these component signals is then used to generate each coefficient. In another embodiment of the present invention, each coefficient is generated in response to at least one of the component signals in the first pair along with a second pair of component signals (I',Q') which are formed by demodulating (54) the incoming signal. This technique can be advantageously adapted to incorporate a number of coefficient updating algorithms and is suitable for use in a number of modulation formats.
