Consider a phase-lock loop (PLL) that is phase locked to a constant frequency reference. Under this condition, the PLL pull-out frequency is defined as the largest input reference frequency step that can be applied without the PLL slipping one or more cycles. The application of an input reference frequency step larger (alternatively, smaller) than the(More)

Many university signal-processing teaching laboratories do not have sufficient resources (both equipment and knowledgeable support personnel) to provide dedicated real-time signal-processing hardware at each student workstation position. Because of this limitation, many students must be content with using personal computers to process non-real time signals(More)
A recently proposed method of reducing target glint errors in radar systems using extended Kalman filtering is further enhanced with the development of a discrete target model and discrete Kalman filter (DKF) that includes clutter effects. Simulation results demonstrating the DKF are presented, and the limits of the usefulness of this method are(More)
This paper is concerned with the stability of a first-order phase-locked loop (PLL) with an input consisting of a desired and an undesired (interfering) sinusoidal signal. This PLL is analyzed for the value of the normalized PLL detuning parameter w/sub /spl Delta//' < 1. This case has been neglected in previous studies. Intuitively, for w/sub /spl Delta//'(More)

Results are given on the phenomenon of data-related false lock in a Costas loop which contains a perfect integrator in its loop filter. The input carrier to the loop is assumed to be biphase-modulated with a T' periodic binary sequence constructed from Manchester symbols; there are p symbols per period. As a result, the false locked loop is described by a(More)
Waveshaping of data bits is used in many digital modulation techniques to control transmission bandwidth. For 99% power-in-channel bandwidth, minimum shift keying (MSK) achieves a channel bandwidth utilization of approximately 1.2 Hz/BPS. While transmitting a message at R/sub b/ bits per second, MSK produces a constant-envelope, continuous-phase, FSK(More)
Sinusoidal frequency modulation yields orthogonal spectral lines from which orthogonal spectral pairs can be formulated. The orthogonal spectral pairs can be utilized as in-phase ('I') and quadrature phase ('Q') signaling waveforms for use in data transmission. This paper describes the origins of these signaling waveforms and the delayed-orthogonal(More)
The sum of a desired tone and an interfering, offset in frequency by v radians/second, tone is considered as the input reference signal for a system comprised of an ideal band-pass limiter and first-order PLL combination. Parameter y denotes the ratio of interfering signal to desired signal amplitudes. In the first of two cases, this two-tone reference(More)
