• ### Instrumentation for Measurement of Cosmic Noise at 2.0 and 2.5 MHz from a Polar Orbiting Geophysical Observatory

Publication Year: 1971, Page(s):86 - 94
| | PDF (2574 KB)

This paper describes the radio astronomy instrument flown on both Polar Orbiting Geophysical Observatories II and IV (OGO-II and OGO-IV). The instrument was designed to map the brightness distribution of cosmic noise over the sky at 2.0 and 2.5 MHz by using the theoretically predicted ionospheric focusing of an electrically short antenna. An antenna impedance bridge was included as a necessary par... View full abstract»

• ### Random Signal Method of Nonlinear Amplitude Distortion Measurement

Publication Year: 1971, Page(s):95 - 99

| | PDF (799 KB)

The degree and orders of nonlinearity of a system can be determined by the use of a random test signal. A Gaussian-distributed random signal with a uniform power spectral density except for a narrow spectral notch is used as an input test signal. The power within the notch at the system output is a measure of the degree of system nonlinearity. Relative variations of the output power within the not... View full abstract»

| | PDF (839 KB)

A variation of the pulse method of junction temperature measurement is presented. The new technique allows the junction temperature of diodes and transistors under stress test to be monitored by a simple procedure. An expression for correcting junction to case thermal resistances, obtained via the steady-state hrb method, for nonthermal effects is derived. Both of these ideas are illust... View full abstract»

Consider a signal generator whose instantaneous output voltage V(t) may be written as V(t) = [V0 + ??(t)] sin [2??v0t + s(t)] where V0 and v0 are the nominal amplitude and frequency, respectively, of the output. Provided that ??(t) and ??(t) = (d??/(dt) are sufficiently small for all time t, one may define the fractional instantaneous frequency deviation... View full abstract»

• ### Simple Voltage-to-Time Converter With High Linearity

Publication Year: 1971, Page(s):120 - 122

| | PDF (1034 KB)

A simple voltage-to-time converter having a high linearity of time/voltage relationship is described. This circuit consists of one monostable multivibrator with a constant current source. The circuit does not have a ramp generator and a voltage comparator. The linearity error of the time/voltage relationship is less than ??0.05 percent for a voltage variation from 0.5 to 14 V.

• ### High-Voltage Video'' Amplifier for Driving Piezoelectric Transducers

Publication Year: 1971, Page(s):122 - 123
| | PDF (370 KB)

An inexpensive wide-band amplifier suitable for driving many piezoelectric transducers encountered in underwater sound propagation studies and laser research is described. Small signal bandwidth is dc to 5 MHz, with large signal response determined by a slew rate limit of 800 V/??s, at maximum output voltage and current of 280 V peak-to-peak and 1 A.

• ### A Two-Port Network Representation Based on an Unsymmetry Factor, With Applications to Coaxial Measurements

Publication Year: 1971, Page(s):123 - 126
| | PDF (1376 KB)

A network representation for linear, passive, and reciprocal two-port devices is described, using as parameters the longitudinal impedance z, the transverse admittance y and the unsymmetry factor k. This representation offers certain advantages in connection with high-frequency and microwave impedance measurements. View full abstract»
