چکیده
The paper gives an automated procedure to design rational decimation compression systems that resample two-dimensional bandpass signals at their Nyquist rates. The procedure takes a sketch of the passband in the frequency domain, circumscribes it with a parallelogram, and linearly maps the parallelogram onto one period of the frequency domain. Thus, the compression system only has linear components.

Automated Design of Two-dimensional Rational Decimation Systems
The paper gives an automated procedure to design rational decimation compression systems that resample twodimensional bandpass signals at their Nyquist rates. Our procedure takes a sketch of the desired bandpass shape in the frequency domain, circumscribes it with a parallelogram of minimal area, and linearly maps the minimal enclosing parallelogram onto one period of the frequency domain. From...
متن کاملEffective Design of a 3×4 Two Dimensional Distributed Amplifier Based on Gate Line Considerations
In this paper two dimensional wave propagation is used for power combining in drain nodes of a distributed amplifier (DA). The proposed two dimensional DA uses an electrical funnel to add the currents of drain nodes. The proposed structure is modified due to gate lines considerations. Total gain improvement is achieved by engineering the characteristic impedance of gate lines and also make appr...
