April 23, 2009[Design View / Design Solution] Using High-Speed Latched Comparators For Simultaneous Instant Frequency Measurement
Measuring key characteristics of high-speed pulses such as frequency, amplitude, and pulse width for simultaneous pulses that overlap in time has long been an issue in design. To solve that problem, engineers developed and refined the monobit receiver. The system includes RF signal shaping and filtering functions, a latched comparator (which is a single-bit analog-to-digital converter, or ADC), a demultiplexer to interface the high-speed digital...
April 23, 2009[Design View / Design Solution] Bandpass Sampling
If a signal is sampled, the spectrum is replicated at every harmonic of the sampling frequency (see the figure). For example, if the spectrum is sampled at 9.2 GHz, the spectrum will repeat at 9.2-GHz intervals, out to plus and minus infinity. As a consequence, the frequency at 4 GHz is indistinguishable from the signal at +13.2 GHz, +22.4 GHz, etc. The opposite is also true—signals at +13.2 GHz and +22.4 GHz, sampled at 9.2...
