Tuberculosis (TB) is one of the leading causes of death from an infectious disease worldwide. India remains to be the country carrying highest burden of the disease. One of the potent problems of present days, in this field, is the emergence of Multi

This paper describes a technique, using the Remez algorithm, to determine the coefficients of the first-order McClellan transformation so that the cut-off frequency of the prototype one-dimensional filter maps onto a contour in the two-dimensional fr

Existing quadrature-modulation systems for bandpass filtering do not make the bandpass filter response have a strictly linear-phase characteristic, even when the equivalent low-pass filter used in the system has a strictly linear-phase response. Simp

Background: Programmatic management of drug-resistant TB (PMDT) under the RNTCP is being implemented in West Bengal in a phased manner since 2011. During the initial years MDR-TB cases were identified based on criteria A. This study examines the firs

A simple design technique for a separable denominator circularly symmetric lowpass filter is described. In this technique an FIR filter function that has a sharp cutoff characteristic and is amenable to efficient implementation is used to meet the tr

A simple technique for designing low-pass recursive digital filters with nearly linear phase characteristic is presented. The linearity of phase is obtained by placing the poles in the neighbourhood of the passband at equal intervals on a circle of r

A technique for designing two-dimensional IIR (infinite-impulse response) filters using a separable transformation function has been reported recently. A modification of this technique is proposed for circularly symmetric filters which gives better r

A modification in the low-pass to bandpass transformation formulated by Broom [1] has been proposed; this is shown to transform a linear-phase low-pass FIR filter to a bandpass filter with approximately linear-phase characteristic and with a constant

The cutoff-slope and stop-band attenuation of low-pass filters with equiripple pass-band behaviour and with multiple pairs of coincident zeros at a suitable frequency in the stop-band have been investigated. Such a filter is shown to have better magn
