An indoor-outdoor garden unit including a basin having an overhead canopy, connected to a water source via a main water tube and holding a plurality of opaque growing trays with removable opaque lids for optimal sprout growth in the dark. The main water supply tube operationally communicates with an on-off timer controlling water cycles. Bottom holes in each growing tray allow water, infused into the basin by any of three selectable mechanisms, to flow upwardly to water the sprouts from underneath, and serve to drain water from the growing trays and to aerate the plants between watering cycles. Sprayers on the underside of each growing tray lid allow watering from the top side. Water can be infused into the basin by the direct basin fill inlet or by a water fountain from which water impacts a water catcher member undermounted on the canopy to shed droplets into the basin.

A system for generating angular modulation comprising a balanced modulator and an adding circuit to which a surface wave device quadrature oscillator applies two signals at the carrier frequency differing 90.degree. in phase, such phase difference being accurately maintained independent of aging and variations in operating temperatures. More particularly, an information signal is applied to one input of the balanced modulator, the output of which is applied to the adding circuit. The surface wave device oscillator completes the system by applying an in-phase carrier frequency to a second input of the balanced modulator and a carrier frequency shifted 90.degree. in phase to a second input of the adding circuit. Angular modulation is thus produced at the output of the adding circuit.

An SWD structure is employed in an FM receiver for signal demodulation and band limiting. An FM signal is applied to the input of an SWD patterned for bandwidth limitation. Two SWD output channels characterized by predetermined differential delays of the modulated input signal are amplitude limited and mixed to produce an audio modulation component.
