Abstract
The receivers were tested to determine the following characteristics: (a) D.C. resistance. (b) Effect of mechanical shock. (c) Impedance at the frequency of primary resonance. (d) Efficiency factor at the frequency of primary resonance. (e) Primary resonance frequency. (f) Magnitude of the secondary resonance peaks. (g) Band width of the primary resonance peak. (h) Band width of the secondary resonance peak.
