摘要： Doppler shift generator for use in electronic countermeasures equipment includes analog memory devices which are comprised of acoustic charge transport (ACT) memory devices. Such Doppler shift generators includes a switch which alternately applies an input signal to said first and second analog memory devices. Each analog memory device is responsive to a clock signal to sample data at a first frequency and to output the data at a second frequency. As a result, a Doppler shifted signal is generated whose frequency has been shifted by the difference in the first and second frequencies.

摘要： There is disclosed an electronic float switch circuit which employs simple immersion probes, one of which is associated with a high fluid level and the other with a low fluid level. Each of the immersion probes operates in conjunction with an oscillator, a detector and a comparator. Essentially, when the associated immersion probe is immersed in a fluid, the oscillator ceases oscillations which therefore provides a first low voltage level via the detector to the comparator to therefore change the state of the comparator. The comparator associated with the high and low level probes operate to set and reset a DC flip-flop which in turn controls an opto-isolator device to trigger a triac. The triac operates the pump. When the fluid level reaches below the level of the low probe, the circuit is disabled allowing the vessel again to be filled with water to allow the pump to operate between the high and low levels by means of the electronic circuit.

摘要： A VSWR protection circuit employs first and second mixers whereby the first mixer receives at one input the transmitted frequency and has a local oscillator coupled to the other input to provide at its output a difference frequency. This difference frequency is applied to the input of the second mixer which also receives at another input a frequency which is the sum of an undesired EMI signal plus a residue signal due to reflection from the transmitter. The second mixer produces difference frequencies according to the output from the first mixer. The output from the second mixer is applied to a narrow bandpass filter which essentially allows the transmitted frequency to propagate. The output from the narrow band filter is then detected whereby a DC control voltage is provided and used as a gain control for the transmitting amplifier and essentially is independent of most interfering frequencies.
